Substances

Question 1

Substances are 1 of 3 types

Answer 1

1. Solid
2. Liquid
3. Gas

Question 2

Solid

Answer 2

-Are very close together
-Vibrating in fixed-position
-In an ordered arrangement
-Held by strong attractive forces

Question 3

Liquid

Answer 3

-Are held close together
-Move around each other
-In a random arrangement
-Held by weaker attractive forces

*vibrating and moving

Question 4

Gas

Answer 4

-Are far apart
-Moving quickly in all directions
-In a random arrangement
-Held by negligible attractive forces

Question 5

Solid metallic substances

Answer 5

-Has layers of metallic atoms
-Held close together by strong metallic bonds
-Forming a giant lattice

Question 6

Solid ionic substances

Answer 6

-Has layers of positive and negative ions
-Held very close together by strong ionic bonds
-Forming a giant lattice

Question 7

Solid molecular substances

Answer 7

-Has layers of molecules
-Held very close together by weak intermolecular forces
-Forming a regular/crystal structure

Question 8

Lattice

Answer 8

an ordered arrangement of particles into rows

Question 9

Giant lattice

Answer 9

when all particles are chemically bonded

Question 10

Regular/Crystal Structure

Answer 10

when all particles are not chemically bonded together

Question 11

Intermolecular force

Answer 11

Weak electrostatic force of attraction that happens between atoms. caused by Dipoles

Question 12

Dipole

Answer 12

Separation of positive and negative charges within a atom.

Question 13

Why are intermolecular forces weak?

Answer 13

When heat comes in contact with dipoles, electrons move around, resulting in dipoles not existing.

Therefore no intermolecular force is present(weak)
