36
Q

When is it a molecular compound/Covalent?

A

When both elements are non-metals

37
Q

How to name a molecular compound/Covalent?

A

Count how many of each atom are in the molecule, use the prefixes to indicate that number
*DO NOT simplify the subscripts

38
Q

Covalent bond

A

A covalent bond involves the sharing of electrons and happens between non-metals

39
Q

What happens to the name of a Cation?

A

It stays the same

40
Q

What happens to the name of an Anion?

A

Change the ending of the anion to -ide

41
Q

What happens to the name of Transition Metal Cations?

A

For transition metal cations, use Roman numerals to indicate the charge

42
Q

What are the exceptions for Transition Metal Cations?

A

Ag, Cd, Zn

43
Q

What happens to the name of Polyatomic ions

A

DO NOT change the name of Polyatomic ions

44
Q

What is the Octet Rule?

A

Atoms tend to gain, lose or share electrons in order to have 8 valence electrons

45
Q

Ion Formation

A

Losing electrons results in a positive ion or cation (metals)
Gaining electrons results in a negative ion or anion (non-metals)
Cations and Anions attract to form an ionic bond (metals + non-metals)

46
Q

What about the rest?

A

Most transition metals can form more than one ion
Exceptions: Ag, Cd, Zn –> Ag+, Cd+2, Zn+2

47
Q

Polyatomic ions

A

Polyatomic ions are charged species that are made of more than one atom

48
Q

Ionic Compounds

A

Ionic compounds need to be neutral overall
The total charge of the cations needs to cancel out the total charge of the anions

49
Q

What are the charges of the transition metal exceptions

A

Ag+, Cd+2, Zn+2
