What comes first when naming an ionic compound?

the cation

What comes first in naming complexes?

the ligands (in alphabetical order)

How is the oxidation state of the central metal atom is designated?

with a Roman numeral in parentheses

If the complex ion has a negative charge?

add "ate" to the name of the metal

What do transition metal complex goes inside when writing the formula?

brackets []

What is written first when writing the formula?

the metal

group 1

alkali metals

group 2

alkaline earth metals

group 7

halogens

group 8

noble gases

isoelectronic

same electron configuration

diamagnetic

all electrons are paired; responds poorly to a magnetic field

paramagnetic

has unpaired electrons; responds to a magnetic field

ligands are usually

Lewis bases

metal centers are usually

Lewis acids

optical/chiral isomers

same arrangement and connectivity of atoms, not the same molecule (have a mirror image)

strucutal/geometric isomers

complexes with the same atoms but different connectivity

linkage isomers

same ligand, bonded through different atoms

ionization isomers

ligand and counter ion switch places

coordination isomers

different metal in the center, same coordination environment (ligands and geometry)

degenerate

of equal energy

lobes

regions in the orbital with high probability of electrons being there

node

regions in the orbital with 0 probability of electrons being there

all tetrahedral complexes are

high spin

allotropes

different forms of the same element

atomic radius trend

increases down a group, decreases across a period

electronegativity trend

increases across a period, decreases down a group

metallic character trend

increases down a group, decreases across a period

synthesis reaction

A + B --> AB

decomposition reaction

AB --> A + B

single-displacement reaction

AB + C --> AC + B

double-displacement reaction

AB + CD --> AD + CB
