Question 36

When is it a molecular compound/Covalent?

Answer 36

When both elements are non-metals

Question 37

How to name a molecular compound/Covalent?

Answer 37

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

Question 38

Covalent bond

Answer 38

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

Question 39

What happens to the name of a Cation?

Answer 39

It stays the same

Question 40

What happens to the name of an Anion?

Answer 40

Change the ending of the anion to -ide

Question 41

What happens to the name of Transition Metal Cations?

Answer 41

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

Question 42

What are the exceptions for Transition Metal Cations?

Answer 42

Ag, Cd, Zn

Question 43

What happens to the name of Polyatomic ions

Answer 43

DO NOT change the name of Polyatomic ions

Question 44

What is the Octet Rule?

Answer 44

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

Question 45

Ion Formation

Answer 45

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)

Question 46

What about the rest?

Answer 46

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

Question 47

Polyatomic ions

Answer 47

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

Question 48

Ionic Compounds

Answer 48

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

Question 49

What are the charges of the transition metal exceptions

Answer 49

Ag+, Cd+2, Zn+2
