CCEA A-Level Chemistry AS 2 Further Physical, Inorganic and Organic overview quiz quiz

Nuclear charge increases while electrons enter the same shell

Electrons are added to a brand new outer shell each time across the period

The amount of inner-shell shielding increases very sharply across the period

The atoms steadily gain extra neutrons in the nucleus across the period

Sodium, because it is a metal with strong metallic bonding throughout

Silicon, because it has a giant covalent structure

Sulfur, because it has eight atoms per molecule

Argon, because it is monatomic with no bonds between atoms

It increases

It stays the same

It decreases

It increases then decreases

The atoms get progressively smaller down the group

The atoms become steadily more electronegative down the group

The overall nuclear charge of each atom decreases down the group

The larger atoms gain an electron less easily
