Periodic Trends

Question 1

Atomic size

Answer 1

Is a function of electron configuration

Question 2

Atomic size increases:

Answer 2

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

Question 3

Isoelectric species

Answer 3

Two atoms or ions that have the same number of electrons

Question 4

Ionization energy

Answer 4

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

Question 5

Ionization increases

Answer 5

The smaller the atom; moving up and two the right

Question 6

Electron affinity

Answer 6

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

Question 7

Electron affinity increases or become more negative

Answer 7

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

Question 8

Electronegativity

Answer 8

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

Question 9

Electronegativity increase

Answer 9

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

Question 10

Hierarchy of electronegativity

Answer 10

… C<br></br>

Question 11

Acidity

Answer 11

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

Question 12

Basicity

Answer 12

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