Q

What happens to group 7 elements the further down the periodic table you go?

A

They become less reactive as the forces exerted by the nucleus are less affective as there is a larger atomic radius and more atomic shielding

Q

Cl2+2KBr goes to what? And why?

Q

What happens to group 1 metals the further down the table you go?

A

They become more reactive because there is a larger atomic radius meaning that the outer electrons experience less of the intermolecular forces. Because there are more electrons between the nucleus and the outer shell more atomic shielding is experienced.
