The Atom

Question 1

what is the mass and charge of a proton?

Answer 1

Relative mass = 1
Relative charge = +1

Question 2

what is the mass and charge of a neutron

Answer 2

relative neutron = 1
relative charge = 0

Question 3

what is the mass and charge of a Electron?

Answer 3

relative mass = 0.0005
relative charge = -1

Question 4

what is the nucleus?

Answer 4

• the nucleus is the middle of the atom containing protons and neutrons
• It has a positive charge because of the protons

Question 5

Describe a Electron

Answer 5

A electron moves around the nucleus in electron shells and they are negatively charged

Question 6
