The elements found in the family are Lithium (Li), Sodium (Na), Potassium (K), Rubidiam (Rb), Chelsium (C), and Francium (Fr). They are very reactive metals.

----------------------------------

NaCl- Common salt used in food

CaCl2- Calcium chloride used as a desinfectant

BaSo4-Barium sulfate used in radiography

LiCi- Lithium Chloride used in Brazing

-------------------------------------

Interesting facts:

- Shiny, soft metals

-They all have one valence electrons in the outer most shell which they seek to lose in order to have a full outer shell, this is what makes them so reactive.

- Low density compared to others

--------------------------------------

Fun facts:

- Low melting and boiling point

- Easy to cut

- Solid

-Most reactive

-the elements are: boron (B), aluminium (Al), gallium (Ga), indium (In), thallium (Tl), and unutrium (Uut)

-they all have 3 valence electrons

-they are all reactive but boron is a little less reactive

-their type of element is metals and metalloids

-compounds that can be made are: Boron Trichloride, and

Borane
-the boron group can be found in: fiber glass, ceramics, and soaps-characteristics: they are they don't conduct electricity well,its not soluble in water, and combines with the oxygen in the air to form boron trioxide

-Interesting facts: their melting point ranges from 29.8 C to 2078 C and that's is definitely a huge difference! Also their atomic mass is relatively 10.8. And their density is 2.34 g/cm to the -3rd power

Magnesium, Beryllium, Calcium, Strontium, Barium and Radium are all parts of the Alkaline Earth Metals.

in all allkaline earth metals there are only 2 valence electrons which makes them very reactive. valence electrons are also known as oxidation numbers which the number is still the same +2

The alkaline earth metals are all types of metals. Calcium can be combined with certain elements and create chalk all of the alkaline metals react with the halogens to make the alkaline earth metal halides. All of the alkaline earth metals can react with water except beryilum to form alkaline hydroxide which needs to be handled with care

FUN FACTS- magnesium and calcium are found in some foods Magnesium and calcium have a number of uses, ranging from building to being found in some foods and dietary systems.  Barium and beryllium are used to make jewelry or are some times used for medicine, while strontium is mostly used in fireworks. Radium, on the other hand, is rarely used outside of labs, partially because its radioactive parts are hazardous to human life.

Nitrogen Group

# data[].attributes.body
Elements found in family

- phosphorus

- arsenic

- antimony

- bismuth

- unanpantium

COMPOUNDS

- to strong to combine with other elements

- halogen,oxygen,hydrogen

- when nitrogen is heated it combines directly with magnesium, lithium, or calcium

USES OF NITROGEN

- annealing stainless steel and other mill products

- liquid nitrogen is used by the oil industry to build up pressure in wells to force crude oil upward

- intert atmosphere in tanks of explosive liquid storage tanks, both in ground-based and in ships

- used by the electronics industry which uses the gas as a blanketing medium during production of such components as transistors diodes.

EXAMPLES Of NITROGEN

- steel manufacturing , used in the process to make steel.

- used to refrigerant

- plants need nitrogen to grow they get the nitrogen out of the soil that they grow in.

- over three quarters of the air is made up of nitrogen

example- lets say you had one hundred pennies take 78 of those pennies and put them to the side that's how much nitrogen is in the air.

REACTIVITY

- its reactive

- oxidation number is +3 or +5, it depends for different elements.

TYPE OF ELEMENTS

-Nitrogen and Phosphorus are nonmetals

- Arsnic and Aintimony are metalloids

- Bismucth is a metal

NUMBER OF VALENCE ELECTRONS

- there are five valence eletrons in the most outer shell

CHARACTERISTICS

- the chemical symbol for the Nitrogen Group is "N"

- The Nitrogen Group is also known as Group 15

FUN FACTS

- Nitrogen makes up 78% of the atmosphere

-  Without nitrogen, the human tissues would not be able to repair itself

Fun facts

Fun facts oxygen does not burn. dry air is 21% oxygen and 78% nitrogen and the other gases are only 1% .

facts! 2/3 of body's mass is oxygen. oxygen's atomic weight is 15.
