Trimester 2 Unit 2

Question 1

What is chemical bonding

Answer 1

when atoms form new, more stable substances

Question 2

What is Ionic Bonding

Answer 2

the positive and negative ions form and attract each other, holding the structure together (it’s a strong bond)

Question 3

Ionic bonding only happens between a

Answer 3

nonmetal and metal

Question 4

Atoms ionically bond to become a

Answer 4

neutral compound

Question 5

when writing ionic formulas always write this first

Answer 5

the metal

Question 6

What do Polyatomic Ions mean

Answer 6

multiple atoms that carry a charge

Question 7

almost all polyatomic ions are

Answer 7

negatively charged

Question 8

if you need multiple of one thing in a polyatomic formula you put it

Answer 8

in parentheses and put a subscript outside

Question 9

generally, names for polyatomic ions end in

Answer 9

-ite or ate

Question 10

why are transition metals special?

Answer 10

they can have multiple charges and form from only positive ions

Question 11

How do we find the charge of a transition metal

Question 22

Step one in finding the charge of a transition metal

Answer 22

identify if it is Ionic or Covalent and if it contains a transition metal

Question 23

Step two in finding the charge of a transition metal

Answer 23

figure out the overall negative charge (-2*2=-4)

Question 24

Step three in finding the charge of a transition metal

Answer 24

divide the overall negative charge by the number of metal atoms you have (-4/1=4)
