Unit 2 Lesson 6: Rational Numbers: Electric Charge
Directions: Read each description and write the associated rational number.
Example: What is the overall charge of a
group with 0 protons and 9 electrons?
What electric charge does this group
have?
1. What is the overall charge of a
group with 1 proton and no
electrons?
What grouping would have the
opposite electric c
harge?
2. What is the overall charge of a
group with 0 protons and 3
electrons?
What grouping would have the
opposite electric c
harge?
3. What is the overall charge of a
group with 10 protons and 10
electrons?
What electric charge does this
gr
oup have?
4. What is the overall charge of a
group with 4 protons and no
electrons?
What electric charge does this
gr
oup have?
Steps:
1. Read the description.
2.
Draw a simple atom (i
f
one is not
given). Pl
ace
protons
in the nucl
eus
and
electrons
around it.
3. Deter
mine wh
ether
there
are more protons
(rendering the group a
positive ion), or
more
elect
rons (rendering the
group a ne
gative ion).
