1
Q

Mendeleev and Meyer

A

Came up with table

2
Q

Atomic radius

A

Decreases left to right
Increases up and down
Up and down takes priority over left to right

3
Q

Size of ions

A

Cations are smaller

Anions are larger

4
Q

Isoelectronic series

A

Ions ha ether same number of electrons plus same electron configuration

Ionic size decreased with an increasing nuclear charge
10 electrons

5
Q

Ionizations energy

A

Minimum energy required to remove an electron

The higher the i.e. The more difficult to remove

Takes more energy each time an electron is removed

Increases across and decreases down

6
Q

Electron affinity

A

Energy accompanying the addition of an electron to a gaseous atom

Typically exothermic

Increases across

7
Q

Electronegativity

A

Ability of an atom in a molecule to attract electrons to itself
Increases left to right decreases
up and down
Closer to F greater the value

8
Q

Metals

A

Compound with transitions metals have colors to them
Li-red or pink Na-orange K-purple
Metals form cations
