structure of an atom

Question 1

what are the sub atomic particles which atoms are made of

Answer 1

protons, electrons, and nuetrons

Question 2

draw and label the atom

Answer 2

nucleus- ball with protons and neutrons
electron shells around nucleus with electrons which orbit it

Question 3

describe the structure of an atom

Answer 3

An atom consists of protons and neutrons in a nucleus. Electrons orbit the electron shells around which is around the nucleus. An electron has a negative charge, a neutron has a neutral charge and protons have a positive charge. A nucleus is made up of neutrons and protons. A nucleus is made up of _neutrons and _protons.

Question 4

proton relative charge, relative mass and location

Answer 4

charge= +1
mass= 1
location= nucleus

Question 5

neutron relative charge, relative mass and location

Answer 5

charge= nuetral (0)
mass= 1
location= nucleus

Question 6

electron relative charge, relative mass and location

Answer 6

charge= -1
mass= 1/2000
location= electron shell
