Periodic trends

Question 1

Size increases in what direction?

Answer 1

Biggest atoms at Bottom left, Smallest at top right.
Size increases down a group

(Size decreases across a period because effective nuclear charge increases across a period)

Question 2

Ionization energy increases in what direction?

Answer 2

Ionization increases from bottom left to Top right (smallest on BL, biggest on TR)

Increases across a period. Decreases down a group

Question 3

Metallic character increases in what direction?

Answer 3

Metallic character increases as you move down a group. Decreases as you move across (Left to right)

Question 4

Which direction does electro-negativity increase?

Answer 4

Electro-negativity increases: Top-Right

Fluorine is the most electronegative

Question 5

Which was does ion and anion sizes increase?

Answer 5

Ion and anion sizes increases down a group
