3. A period in a periodic table helps sort out where all the elements stay and how they are grouped
4.

ATOM: one element from the periodic table.

ELEMENT:  Multiple of the same atoms bonded together.

# data[].attributes.body
Atom:

The definition of an atom is the smallest component of an element, characterized by a sharing of the chemical properties of the element and a nucleus with neutrons, protons and electrons.

Element:
An element is a substance whose atoms all have the same number of protons: another way of saying this is that all of a particular element's atoms have the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions

Compound:

A compound is a substance formed when two or more chemical elements are chemically bonded together. ... Water: two hydrogen atoms bonded to an oxygen atom. The type of bonds holding elements together in a compound can vary: two common types are covalent bonds and ionic bonds

Mixture:

Definition of Mixture. Any substance that has a uniform and unchanging composition is considered to be pure. Examples of pure substances include elements. A mixture is a combination of two or more pure substances in which each pure substance retains its individual chemical properties.

Questions:
Is it posible to have a monatomic compound?
It is not possible to have a Monomatic compound because compounds must always have two or more elements.

Explain why a diatomic molecule can be an element or a compound.

the smallest particle of a chemical element that can exist.

Atom:
The smallest particle of chemical element that exist. An atom usually consists of protons, neutrons, and electrons. With the neutrons and the protons existing within the nucleus and the electrons orbiting the nucleus.

Molecule of Element: Two or more atoms joined together

Molecule of a Compound: two different atoms joined together

# data[].attributes.body
a substance formed from two or more elements chemically united in fixed proportions

# data[].attributes.body
The periodic table is a overview of all the elements the earth has. It also splits the elements into groups. Each element has its own number.

# data[].attributes.body
Monatomic means "single atom". Chemical elements in the gas phase will all be Monatomic.
Example: Hydrogen, Helium
Diagram:

Diatomic element

A mixture is a material made up of two or more different substances, which are mixed

# data[].attributes.body
"A Single Atom" applied to a gas for example where atoms are not bound to each other.

# data[].attributes.body
The groups are visible on the periodic table. The numbers of the groups can be found on the top of the periodic table.

# data[].attributes.body
Molecules composed of only two atoms of the same or different chemical elements

# data[].attributes.body
A material that only consists of one type of atom, and not a mixture of different ones. Elements cannot be further broken down into seperate parts that are individual materials.

Arrangement of the chemical elements ordered by their atomic number.

# data[].attributes.body
Groups in the Periodic Table are also known as columns of elements. There are 18 numbered groups in the Periodic Table.

# data[].attributes.body
a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.

# data[].attributes.body
Any substance that isn't chemically bonded. Pure substances that are together.
