1st ionisation energy decreases.

Front

What happens to the 1st ionisation energy as you go down Group 17?

Back

1st ionisation energy decreases.

Front

Define electronegativity.

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

What is the trend of atomic radius in Group 2 as you go down the group?

Back

Atomic radius increases.

Front

What is the trend of atomic radius in Group 17 as you go down the group?

Back

Atomic radius increases.

Front

Explain the trend in melting points of Group 2 elements as you go down the group.

Back

Melting points generally increase due to stronger metallic bonding.

Front

Explain the trend in boiling points of Group 17 elements as you go down the group.

Back

Boiling points increase due to increased van der Waals forces.
