Question 12

Octet Rule

Answer 12

tendency of atoms to have eight electrons in
the valence shell

Answer 20

nonmetal + nonmetal

Question 21

sharing of electrons

Answer 21

Covalent Bond

Question 22

2 Types of Covalent Bond

Question 23

Metallic Bond

Answer 23

metals + metals

Question 24

Electronegativity

Answer 24

ability of elements to attract valence electrons

Question 25

Electronegativity Difference

Answer 25

The difference between the electronegativities of two atoms determines the type of bond that can be formed between atoms. (Absolute Value)

Nonpolar Covalent EN

Answer 26

<0.4

Question 27

Nonpolar covalent shape

Answer 27

symmetric

Question 28

Why is nonpolar symmetric?
