Module 3

Question 1

Chemical bonds

Answer 1

Attractions between atoms that hold atoms and molecules together.

Question 2

Hydrogen bonds

Answer 2

Interaction with partially positive hydrogen atom and partially negative atom with an unshared pair of electrons.

Question 3

Neutron

Answer 3

Neutral charge that is contained in the nucleus and has a mass of 1 atomic mass unit.

Question 4

Covalent bonds

Answer 4

Sharing of electrons. Negatively charged between atoms, the number of covalent bonds that can form is dictated by the number of unpaired electrons in the outer shell.

Question 5

Ionic bonds

Answer 5

Attraction between a positive and negative ion. No electrons sharing occurs in the bond. Transferred from one atom to another.

Question 6

Proton

Answer 6

Positively charged that is contained in the nucleus and a mass of 1 atomic mass unit.

Question 7

Electronegative

Answer 7

Holds more shared electrons close.

Question 8

Electrons

Answer 8

Negatively charged partial that occupies shells surrounding the nucleus and has a mass that is small.
