They are uncharged

Question 10

How many electrons can hold on the first shell?

Answer 10

2

Question 11

How many electrons can hold on the second shell?

Answer 11

8

Question 12

How many electrons can hold on the third shell?

Answer 12

up to 18

Question 13

What are found in the nucleus?

Answer 13

Protons and neutrons

Question 14

Why does the nucleus of an atom have a positive charge?

Answer 14

This is because the nucleus of the atom consists of protons which are positively charged and neutrons which have no charge.

Question 15

Why do electrons orbit the nucleus?

Answer 15

The nucleus attracts the Electrons which are negatively charged.

Question 16

An atom is electrically neutral or______

Answer 16

uncharged

Question 17

Why is an atom uncharged?

Answer 17

Because in an atom, the number of electrons is equal to the number of protons. This means that the amount of positive charge is equal to the amount of negative charge.
