1
Q

Atomic size

A

Is a function of electron configuration

2
Q

Atomic size increases:

A

As you move towards the left and down in the periodic table

3
Q

Isoelectric species

A

Two atoms or ions that have the same number of electrons

4
Q

Ionization energy

A

Energy required for the removal of an electron from a neutral atom; requires input of energy (endergonic process)

5
Q

Ionization increases

A

The smaller the atom; moving up and two the right

6
Q

Electron affinity

A

The amount of energy involved in adding a single electron to an isolated gas-phase atom; process liberated energy (exergonic process)

7
Q

Electron affinity increases or become more negative

A

As you move up and to the right on the periodic table

8
Q

Electronegativity

A

The ability of an atom in a molecule to polarize binding electrons toward itself

9
Q

Electronegativity increase

A

As you move up and to the right on the periodic table

10
Q

Hierarchy of electronegativity

A

… C<br></br>

11
Q

Acidity

A

Increases as one moves down and to the right on the periodic table

12
Q

Basicity

A

Increases as one moves up and to the left on the periodic table
