The Atom

Question 0

Name the three sub-atomic particles of an atom

Answer 0

Protons
Neutrons
Electrons

Question 1

Explain an atom

Answer 1

The smallest part of an element which still has the properties of that element.

Question 2

What is a proton

Answer 2

It’s a sub-atomic particle in the atom contained in the nucleus, it has a mass of 1 and a positive charge

Question 3

Explain a neutron

Answer 3

Is a sub-atomic particle in the atom contained in the nucleus. It has a mass of 1 and a neutral charge. The number of neutrons in a nucleus determines the isotope of that element.

Question 4

What is an electron

Answer 4

Mass is negligible( very small ) and they have a negative charge, they orbit the nucleus

Question 5

Explain the mass number

Answer 5

Amount of protons and neutrons together in an element

Question 6

Explain atomic number

Answer 6

Number of protons in an element

Question 7

Up to how many shells can an atom have

Answer 7

8

Question 8

How many electrons go in each she’ll

Answer 8

First-2

Second,third, fourth,fifth,sixth,seventh,eighth-8

Question 9

Explain isotopes

Answer 9

Atoms of the same element which have different numbers of neutrons.

Question 10

What was the name of the scientist who was the first person to put forward the idea of electron shells containing electrons orbiting the nucleus

Answer 10

Niels Bohr

Question 11

Name two isotopes

Answer 11

Carbon13

Carbon14

Question 12

What are the properties of an isotope

Answer 12

They have the same atomic number of that element but a different mass number
