APHY101Ch2Chemistry4-6

This is formed when two or more atoms combine

Depicts the numbers and kinds of atoms in a molecule

Shows how atoms bond and are arranged in a molecule

The region of space electrons occupy one or more of

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

Cannot form chemical bonds

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

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

Atoms that gain or lose electrons and become electrically charged

Atoms that become positively charged because they lost electrons

Atoms that become negatively charged because they gain electrons

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

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

Specialized molecule in which electrons are not shared equally

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

Substances being changed in a chemical reaction

Substances formed at the end of a chemical reaction

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

Occurs when the bonds of a reactant molecule break from simpler molecules

Occurs when parts of two different kinds of molecules trade positions

Occurs when products can change back to the reactant or reactants

Molecules that influence the rates of chemical reactions but are not consumed in the reactions

What happens to the charge of an atom if it either gains or loses an electron?

Why do atoms combine with other atoms?
