Energy 5.3- Electric Enegry

Question 1

What charge does an electron have?

Answer 1

Negative.

Question 2

What charge does a proton have?

Answer 2

Positive.

Question 3

What charge does a neutron have?

Answer 3

Neutral, no charge.

Question 4

What charge does an overall atom have?

Answer 4

The opposite charges balance each other out and so the atom has no overall charge.

Question 5

What is static energy?

Answer 5

Static energy is the build-up of electric charge on a surface. The build-up of charge most commonly occurs because the surface has been rubbed against another. Electrons have been rubbed off one surface (charging it positive) and have transferred to the other surface (charging it negative).

Question 6

What is current electricity?

Answer 6

The flow of charged particles, such as electrons or ions, moving through a wire

Question 7

What is an ion?

Answer 7

Electrons get rubbed/knocked/pulled off an atom, which leaves the atom with more protons, giving it an overall positive charge. This is known as An ion (Charged atom).

Question 8

What can cause an atom to become an ion?

Answer 8

The loss of electrons
