TERM 1
GROUND STATE
DEFINITION 1
The lowest-energy configuration of an atom.
TERM 2
PARAMAGNETIC SUBSTANCE
DEFINITION 2
A substance that is weakly attracted by a magnetic field,
usually as the result of UNPAIRED ELECTRONS.
TERM 3
DIAMAGNETIC SUBSTANCE
DEFINITION 3
A substance that is weakly repelled by a magnetic field,
usually because it has ONLY PAIRED ELECTRONS.
TERM 4
BASIC OXIDE
DEFINITION 4
Reacts with acids. Most metal oxides are basic. If soluble,
their water solutions are basic.
TERM 5
ACIDIC OXIDE
DEFINITION 5
Reacts with bases. Most nonmetal oxides are acidic. If
soluble, their water solutions are acidic.
