Question 5

Compound

Answer 5

Question 6

Octet rule

Answer 6

Atoms will bond together so that each atoms attains an electron arrangement with 8 electrons in its outermost shell.

Question 7

Ionic bonding

Answer 7

Is when one atom gives electrons and the other atom takes electrons to get a full outer shell.

Question 8

Covalent bonding

Answer 8

Is when both atoms share electrons to get a full outer shell.

Question 9

Single covalent

Answer 9

Single covalent bonds occur when atoms share one pair of electrons.

Question 10
