Answer 27

Attraction or repulsion between any two charged objects.

Question 28

The strength of the Electric forces depends on what?

Answer 28

The strength of an electric force depends on the size, or magnitude, of the charges and the distance between them.

What are negative charges?

Answer 29

Electrons

Question 30

What are positive charges?

Answer 30

Protons

Question 31

What charges repel?

Answer 31

Like charges will repel. The charges will push each other away.

Question 32

What charges attract?

Answer 32

Unlike charges will attract. The charges will push each other together.

Question 33

What happens when electrons move easily from one atom to another?

Answer 33

Imbalance of electrons

Question 34

If an atom has an equal number of protons and electrons.

Answer 34

Then, the atom is electrically neutral, no electrical charge.

Question 35

If an atom has an unequal number of protons and electrons...

Answer 35

Then, the atom is electrically charged.

Question 36

It is an atom or molecule that has an electric charge.

Answer 36

Ion

Question 37

What makes an atom different from an ion?

Answer 37

An atom is electrically neutral; the same number of protons and electrons; and the number of protons identify the element.

Question 38
