Answer 10

4f

Question 11

Atomic radius … from left to right across a period in the periodic table

Answer 11

Atomic radius … from top to bottom within a group in the periodic table

Question 12

What does it mean that electrons in the highest energy levels are “shielded” by those in lower energy levels?

Answer 12

The inner electrons repel the outer electrons, so the outer electrons are attracted to the positively charged nucleus and the slight repulsion of the inner electrons. The repulsion partially cancels out the attraction, thus ‘shielding’ the outer electrons from the full attractive force of the nucleus.

Question 13

Why does ionization energy increase from left to right along a period?

Answer 13

The nuclear charge increases across the period, but the shielding effect remains constant. So, there is an increase in the attraction of the nucleus for an electron.

Question 14

Electronegativity generally …. from left to right across a period and … from top to bottom within a group of the periodic table.

Answer 14

increases; decreases
