Unit 4: Classifcation and Naming Ions

Question 1

Polyatomic Ion

Answer 1

Two or more atoms with charge

Question 2

Cation

Answer 2

Positive ion
Forms from a loss of electrons
Metals form this

Question 3

Anion

Answer 3

A negative ion
Forms from a gain of electrons
Nonmetals form this

Question 4

Binary compound

Answer 4

Two elements

Question 5

Ternary compound

Answer 5

Three or more elements

Question 6

Ionic compounds

Answer 6

A bond formed from the transfer of electrons (one atom loses, another gains)

Question 7

Ionic properties

Answer 7

High melting points and boiling points

Conducts energy when dissolved or molten

Question 8

Covalent compounds

Answer 8

Forms when two atoms share electrons so they can both satisfy the octet rule (no charge)

Question 9

Covalent properties

Answer 9

Low boiling and melting point

Do not conduct electricity b/c no ions

Question 10

Acids

Answer 10

Hydrogen bonded to another nonmetal

Question 11

Polar Covalent Bonds

Answer 11

Atoms are not sharing electrons

Question 12

No polar covalent bonds

Answer 12

Atoms are equally sharing electrons

Question 13

Monotomic Ion

Answer 13

One atom
