specific gravity
= density of liquid/ density of water
-
mass number
proton + nutron
-
cation
becomes positively charged via loss of electrons
-
anion
becomes negatively charged via gain of electrons
-
A
Representative electrons
-
B
transition elements, normally 2 valence electrons
-
atomic size
down and to the left = increasing size
-
ionic size
metal atoms are bigger
-
electron affinity
up and to the right = increasing
-
ionic bond
- METAL + NONMETAL
- ENDING SOUND ALWAYS "IDE"
- high boiling and melting point
- conducts electricity
- soluble in water, insoluble in non polar organic solvent
-
remember
- Cu+1 Cu+2Hg+1 Hg+2 Fe+2 Fe+4
- Sn+2 Sn+4
- Pb+2 Pb+4
-
covalent bond
- NON METALS SHARING VALENCE ELECTRONS
- USE PREFIXES IN NAMING
- low boiling point and melting point
- do not conduct electricity
- soluble in non-polar solvent
-
