A

Gain electrons

17
Q

When a metal and a non metal bond what is the overall charge

A

Zero

18
Q

What is hunds rule

A

Electrons prefer to occupy orbitals on their own

19
Q

What is covalent bonding

A

Bonding involving the sharing of outer shell electrons

20
Q

What is hydrogen bonding

A

Similar to the permanent dipole the electron pair dragged away from hydrogen leaving an exposed nucleus and this amplifies the force of attraction

21
Q

A

+1 ions

22
Q

What ions do group 2 metals form

A

+2 ions

23
Q

What ions do group 3 elements form

A

+3 ions

24
Q

A

-1 ions

25
Q

What ions do group 6 elements form

A

-2 ions

26
Q

Describe monoatomic

A
