Transition metal:

Many scientists describe a "transition metal" as any element in the d-block of the periodic table, which includes groups 3 to 12 on the periodic table. In actual practice, the f-block lanthanide and actinide series are also considered transition metals and are called "inner transition metals".

Hello students! You are carrying on with an excellent work, according to the following European key competences, I introduced during the first lesson.
My compliments!

"SUMMARY OF:

Recommendation 2006/962/EC on key competences for lifelong learning

WHAT IS THE AIM OF THIS RECOMMENDATION?

It urges EU governments to make teaching and learning of key competences part of their lifelong learning strategies. The recommendation identifies 8 key competences that are fundamental for each individual in a knowledge-based society.

KEY POINTS

The 8 key competences are the following:

1.

Communicating in a mother tongue: ability to express and interpret concepts, thoughts, feelings, facts and opinions both orally and in writing.

2.

Communicating in a foreign language: as above, but includes mediation skills (i.e. summarising, paraphrasing, interpreting or translating) and intercultural understanding.

3.

Mathematical, scientific and technological competence:sound mastery of numeracy, an understanding of the natural world and an ability to apply knowledge and technology to perceived human needs (such as medicine, transport or communication).

4.

Digital competence: confident and critical usage of information and communications technology for work, leisure and communication.

5.

Learning to learn: ability to effectively manage one’s own learning, either individually or in groups.

6.

Social and civic competences: ability to participate effectively and constructively in one’s social and working life and engage in active and democratic participation, especially in increasingly diverse societies.

7.

Sense of initiative and entrepreneurship: ability to turn ideas into action through creativity, innovation and risk taking as well as ability to plan and manage projects.

8.

Cultural awareness and expression: ability to appreciate the creative importance of ideas, experiences and emotions in a range of media such as music, literature and visual and performing arts".

Halogen: is one of a group of chemical elements that includes: chlorine, fluorine and iodine. Halogens  are often used in lighting and heating devices.
Hydrogen: is a colourless gas that is the lightest and commonest element in the universe.
Hazard symbols:are recognisable symbols used for dangerous materials,locations, or objects.
Helium: is the chemical element of atomic number 2, an inert gas which is the lightest member of the noble gas series.
Iron: is a chemical element with symbol Fe(from Latin:ferrum) and atomic number 26 it’s a metal in the first transition series. It’s by mass the most common element on earth,forming much earth’s outer and inner core.
Iodine: the chemical element of atomic number 53,a non-metallic element forming black crystals and violet vapour.A solution of iodine is alcohol used as a mild antiseptic.

The alkaline earth metals are six chemical elementsin group 2 of the periodic table. They are beryllium(Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.
Structurally, they have in common an outer s- electron shell which is full ;that is, this orbital contains its full complement of two electrons, which these elements readily lose to form cations with charge +2, and an oxidation state of +2

All the discovered alkaline earth metals occur in nature.[6] Experiments have been conducted to attempt the synthesis of element 120, the next potential member of the group, but they have all met with failure.

Group (periodic table): in chemistry, a group is a columb of elements in the periodic table of the chemical elements. There are a 18 numbered groups in the periodic table, and the fblock columns are not numbered.
Gas(noble gases): the noble gases make up a group of chemical elements with similar properties;under standard conditions, they are all odorless,colorless,monatomic gases with very low chemical reactivity. The six noble gases that occur naturally are all nonmetals. Oganesson(Og) is variously predicted to be a noble gas as well or to break th trend due to relativistic effects;its chemistry has not been investigated

Difference between metals and not metals (lavoro di gruppo) :

The metals and not metals are found in the periodic table. They are separated by a zig-zag line. The metals are in the 1st and 2nd group and in the others groups at the left of this line.
Sodium, Potassium and Iron are very reactive metal.
The not metals are in the right of this line and they are less reactive than the metals.
Example:
• Clorium (Cl) ---> is a halogen
• Neon (Ne) ---> is a noble gas

Mendelev's periodic table (lavoro di gruppo)

The simbols in chemistries are universal.
Metals give electrons and non metals share electons.
The atom can become a cation. An atom that hasn't all the electrons.
An anion is an atom that have gaened electons.
The First group is composed of elements that have one electon on the valence shell (Na)
The second group is composed of elements that have two electrons on the valence shell. In it we can find metals as (Ca). It has eight electrons on the valence shell if it has given away two electrons. Because has a low electronegativity. It becomes a cation (ion)
In the third group we find metals and not metals like (Al).
In the fourth group we find metals and not metals (Pb).
In the fifth group we find five electrons on the valence shell. Therefore these elements are all not metals as (N) and (P).
In the sixth we find six electrons on the autest shell. They are all not metals a part from (Po). Oxiges is a very reactive element volved in oxidation (FeO).
In the seventh group we have seven electrons on the valence shell. They are all not metals and they are called halogens as (Cl) or (F). They arrive at eight electrons if the valence shell receive an electron for example from (Na). Therefore they became anions: (Cl-).
Halogen means salt formers (NaCl)
Noble gases has eight electrons on the valence shell so they are called inert (He)
The transition metals are the metallic elements that serve as a bridge or transition between the two sides of the table

Ductile:  "Ductility is a physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking. A ductilesubstance can be drawn into a wire. Examples: Most metals are good examples of ductilematerials, including gold, silver, copper, erbium, terbium, and samarium."

Chromium is a chemical element with symbol Cr and atomic number 24. It is the first element in group 6. It is a steely-grey, lustrous, hard and brittle transition metal.Chromium boasts a high usage rate as a metal that is able to be highly polished while resisting tarnishing. Chromium is also the main component of stainless steel, a popular steel alloy due to its uncommonly high specular reflection. Simple polished chromium reflects almost 70% of the visible spectrum, with almost 90% of infrared light waves being reflected.The name of the element is derived from the Greek, meaning color, because many chromium compounds are intensely colored.

Bromine: "Bromine is a chemical element with symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodine. Elemental bromine is very reactive and thus does not occur free in nature, but in colourless soluble crystalline mineral halide salts, analogous to table salt."

Base: in chemistry a base thought of as a substance which can accept protons or any chemical compound that yields hydroxide ions (OH⁻) in solution. It is also commonly referred to as any substance that can react with an acid to decrease or neutralize its acidic properties, change the color of indicators (e.g. turn red litmus paper blue), feel slippery to the touch when in solution, taste bitter, react with acids to form salts, and promote certain chemical reactions (e.g. base catalysis). Example of simple bases are sodium hydroxide and ammonia.
