Question 2

Properties of protons

Answer 2

In the centre of the nucleus and have a relative charge of +1 and has a relative mass of 1

Question 3

Properties of a neutron

Answer 3

In the nucleus and has no relative charge and relative mass is 1

Question 4

Properties of electrons

Answer 4

In the outer of the atom (in the shell) and have a negative charge -1 or 1/2000

Question 5

Atomic number

Answer 5

It is equal to the number of protons in the nucleus

Question 6

Mass number

Answer 6

Total number of protons and neutrons in the nucleus

Question 7

Isotopes

Answer 7

Isotopes are variants of a particular chemical element which differ in neutron number

Question 8

Group number

Answer 8

This shows the amount of electrons on the last shell of the atom

Question 9

Period number

Answer 9

The number that is given to a group of elements across the periodic table

Question 10

Electron arrangement

Answer 10

Its the way electrons are arranged around the atom on the shells

Question 11

Electrons

Answer 11

Have a relative mass of 1/2000 and have a -1 charge. The are equal to the number of protons(ONLY FOR ATOMS NOT IONS)
