1.2.7 Electricity

​Note Book

Page 17

A form of energy that results from charged particles

They can attract and repel each other

Caused by electrons

​

Electricity

Nucleus

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

​
Let's check out how they work!

​Electrical force

​Opposites Attract

​​Two Negatives Repel

​​Two Positives Repel

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

​

​Electric Field

Positive to Negative

Create an Attraction

​​Interactions

​Negative to Negative

Creates Repulsion

Positive to Positive

Creates Repulsion
