This is formed when two or more atoms combine molecule

Depicts the numbers and kinds of atoms in a molecule molecular formula

Shows how atoms bond and are arranged in a molecule structural formula

The region of space electrons occupy one or more of electron shells (energy shells)

This is when the outer shell attempts to be filled to 8 electrons octet rule

Cannot form chemical bonds inert

Electron in the outer shell of atom that can combine with other atoms to form molecules valence electrons

Atoms that are not reactive and have completely full outermost electron shells inert atoms

Atoms that gain or lose electrons and become electrically charged ions

Atoms that become positively charged because they lost electrons cations

Atoms that become negatively charged because they gain electrons anions

Bond formed between two opposite charged ions (between an anion and cation) ionic bonds

Formed when atoms share electron in an attempt to fill the outer shell covalent bond

Specialized molecule in which electrons are not shared equally polar

Formed by the attraction of a positive hydrogen end of a polar molecule to the negative nitrogen or oxygen end of another polar molecule hydrogen bond

Substances being changed in a chemical reaction reactants

Substances formed at the end of a chemical reaction products

Occurs when two or more atoms, ions, or molecules bond to form a more complex structure synthesis reaction
