1- proton - positive charge

2- neutron - neutral



Outside

1- electrons - negative charge

​

​Atom Parts

​If an atom loses an electron it becomes positively charged

If an atom gains an electron it becomes negatively charge

​Usually an atom has an equal number of protons and electrons

is the attraction or repulsion between charged objects


similar to magnetism

Multiple Choice

Which of the following statements best explains what occurred in the picture?

• hair and balloon both have negative charge & attract each other

• balloon is negative & hair positive so attract each other

• balloon and hair negative so they repel each other

​Let's Look at some Unique Electric Events!

the area of electrical force around a charged particle


always flows away from a positive charge

​Electric Field

Negative charge points toward the particle




So go from positive to negative charge
