Groups

Question 1

metals

Answer 1

conductors, high melting points, high boiling points, ductile, malleable, react by losing electrons

Question 2

non metals

Answer 2

electrical insulators, low melting points, low boiling points, brittle, gain electrons when reacting with metals

Question 3

high number of shells

Answer 3

more shielding = less electrostatic attraction between outer electrons and nucleus, more easy to lose/ gain electrons
