basic chemistry

If Gas, liquid, and solids were broken down into the smallest elemental units, it would be composed of:

• compounds

• atoms

• comlex molecules

• elements

Atoms contain an equal number of

• neutrons & protons

• protons & electrons

• neutrons & electrons

A positively charged ion:

• anion

• neutron

• cation

• electron

Negatively charged ion:

• proton

• anion

• cation

• neutron

Protons and Neutrons are both located in the:

• Nucleus

• circle around nucleus

• Nucleolus

• membrane

When an atom loses or gains a charge it becomes a/an:

• isotope

• nitrogen

• element

• ion

Many atoms with the same number of electrons and protons and same chemical properties

• molecule

• compound

• atom

• element

How are elements identified

• atomic mass

• # of isotopes

• atomic number

• # of cations

What determines the atomic number

• #of neutrons

• #of protons

• # of atoms

• #of cations

What determines the mass number?

• # of electrons and protons

• # of anions and neutrons

• # of protons and nueutrons

• # of valence shells
