Question 5

Compound

Answer 5

When two or more atoms of different elements have a chemical bonding joining together.

Question 6

Octet rule

Answer 6

Alone will bond together so that each atom attains an electron arrangement with 8 electrons in its outermost shell

Question 7

Ionic bonding

Answer 7

One atom gives electrons and the other atom takes electrons to get full outer shell

Question 8

Covalent bonding

Answer 8

Both atoms share electrons to get a full outer shell
