Question 14

What is meant by “sea of electrons”

Answer 14

Electrons flow through metals

Question 15

What are 3 properties of metals

Answer 15

Good conductors of heat, electricity, and light

Question 16

Chemical compounds tend to form so
that each atom has an octet of
electrons in its highest occupied energy
level is a statement called what?

Answer 16

Octet Rule

Question 17

How are chemical bonds formed

Answer 17

They tend to form so that each atom can either gain, lose, or share electrons to have 8 in their highest energy level

Question 18

Intermolecular Forces

Answer 18

Forces of attraction between molecules- specifically polar

Question 19

Explain the impact of intermolecular forces on boiling and evaporation points

Answer 19

They can impact boiling and evaporation points because if they have weaker dipole then they can boil and evaporate quicker than if they had a strong dipole.

Question 20

The property of metals stating that
they can be drawn into a wire is called what?

Answer 20

ductility

Question 21

The ability of a metal to be hammered
into thin sheets is called what?

Answer 21

malleability

Question 22

This force is very weak, only happens
momentarily, and only occurs in
nonpolar molecules.

Answer 22

London dispersion forces

Question 23

T or F: Dipole-dipole forces are
forces of attraction between polar
molecules.

Answer 23

True

Question 24

Simplest collection of atoms from
which an ionic compounds formula
can be established is called a what?

Answer 24

formula unit

Question 25

Bond in which the bonding electrons
are shared equally is called _____.

Answer 25

nonpolar covalent

Question 26

Bond in which the bonding electrons
are not shared equally is called
_____.

Answer 26

polar covalent

Question 27

True or False: As bond energy
increases, the length of the bond
gets longer.

Answer 27

false, the higher the energy needed to
break the bond, the shorter the bond.

Question 28

A neutral group of atoms that are held
together by covalent bonds is called
a(n) _____.

Answer 28

molecule

Question 29

A pair of electrons that are not
involved in a chemical bond is called
a(n) _____.

Answer 29

unshared pair

Question 30

Attraction between a hydrogen atom
and an unshared pair of electrons on a
N, O, or F atom on a nearby molecule is
called a(n) _____.

Answer 30

hydrogen bond
