2.3 Chemical Bonds

Question 1

What happens with electrons during non polar bonds?

Answer 1

equal sharing of electrons

Question 2

What happens with electrons during ionic bonds?

Answer 2

no sharing of electrons in bond

Question 3

What happens with electrons during polar bonds?

Answer 3

unequal sharing of electrons

Question 4

Differentiate between a polar and non polar covalent bond

Answer 4

In polar the bonding electrons share unequally between two atoms, in non polar the bonding electrons share equally

Question 5

How does electronegativity determine what type of bond two atoms will form?

Answer 5

ionic bonds have a larger difference in electronegativity and covalent bonds will result in a smaller difference

Question 6

What type of bond will form between Mg and Cl, and why?

Answer 6

ionic bond because the oppositely charged magnesium and chloride ions attract one another.

Question 7

How do ionic substance dissolved in water?

Answer 7

separate in atoms

Question 8

How do covalent substance dissolved in water?

Answer 8

separate in molecules

Question 9

What does bonding provide?

Answer 9

it provides stability
