Elements, Atoms, Molecules, Ions, Ionic and Molecular Compounds, Cations vs Anions, Chemistry

ATOMS

building blocks of matter

MOLECULES

made when two or more atoms bond together.

PURE ELEMENT

a substance that is made up of only one kind of atom

COMPOUND

a substance made from two or more different elements that have been chemically joined

ELECTRONS

have negative charge

PROTONS

have positive charge

NEUTRONS

neutrals

ATOMS

number of protons = number of electrons

formula to get the electron

atomic number - charge = electrons

ION

charged atoms

electron > proton

if there’s negatively ion, there are more

proton > electron

if there’s a positively charged ion there are more

CATION

positively charged (lost electrons)

negatively charged (gain electrons)

ANION

TWO TYPES OF COMPOUND

ionic & covalent compound

composed of metals/non-metals

IONIC COMPOUND

MOLECULAR/COVALENT COMPOUND

composed of non-metals
