Ionic Bonds And Covalent Compounds

Question 1

Characteristics of an ionic bond

Answer 1

Higher boiling points
Solid, crystal like
Soluble in water
Less flammable
Conductive in water

Question 2

What are cations and anions?

Answer 2

Cations are positive ions and anions are negative ions

Question 3

What is the naming rule for ionic compounds?

Answer 3

Name the metal first and then change the non metal to -ide

Question 4

What is a covalent compound vs ionic compound?

Answer 4

Covalent compounds are 2 non metals bond and ionic compounds are a metal and non metal bond

Question 5

Characteristics of a covalent bond

Answer 5

Lower melting and boiling points
Solid, liquid, gas
Less soluble
More flammable
Not Conductive

Question 6

What is the octet rule?

Answer 6

The octet rule states that atoms tend to bond in a way so that they have 8 electrons in their valentine shell

Question 7

What is combining capacity?

Answer 7

Combining capacity is the number of covalent bonds that a non metal atom will usually make to form a stable molecule.

Question 8

How do you name covalent compounds?

Answer 8

The first atom starts with mono, di, tri, etc, and the second atom is changed to -ide (also add mono, di, tri, etc).

Question 9

What are diatomics?

Answer 9

Diatomics are elements that can only exist as two atoms of the element, they cannot exist as single atoms. Remember the term HOFBrINCL.
