Ions

Question 1

Name some sub-atomic particles

Answer 1

Protons, Neutrons and Electrons

Question 2

What is the relative charge and mass of a Proton

Answer 2

Relative charge= +1

Relative Mass=1

Question 3

What is the relative charge and mass of a Neutron

Answer 3

Relative charge= 0

Relative Mass=1

Question 4

What is the relative charge and mass of an Electron

Answer 4

Relative charge= -1

Relative Mass= 1/1835 OR Negligible

Question 5

What does the Group Number show and where is it shown in the periodic table

Answer 5

How many electrons are in the outer shell of an atom, shown in columns

Question 6

What does the Period Number show and where is it shown in the periodic table

Answer 6

How many shells are in an atom, shown in rows

Question 7

What is an Ion

Answer 7

A charged atom/ group of atoms. It’s charged because it has lost or received electrons.

Question 8

What does the Mass Number show

Answer 8

How many Neutrons and Protons are in an atom

Question 9

What does the Atomic Number show

Answer 9

How many Protons ( and electrons to balance out the charge) are in an atom

Question 10

How do atoms form Ions

Answer 10

Atoms can gain or lose electrons to form Ions

Question 11

Why do atoms form Ions

Answer 11

Atoms can gain or lose electrons to get a full outer shell. This makes them more stable

Question 12

Why are Ions charged

Answer 12

Atoms normally have the same number of protons and electrons so they are neutral overall. If an atom loses an electron, it gets a charge of +1 as it has more protons than electrons. If an atom gains an electron, it gets a charge of -1 as it has more electrons than protons.

Question 13

What is the maximum amount of shells an Atom could have

Answer 13

8 Shells

Question 14

What is the Sub-Atomic particle in the shells of an atom

Answer 14

Electrons

Question 15

What are the Sub-Atomic particles in the Nucleus of an atom

Answer 15

Protons and Neutrons

Question 16

How can you tell the difference between Protons and Neutrons in the Nucleus

Answer 16

1 Sub-atomic particle will be coloured in and the other won’t. The Sub-atomic particles which have the same amount of Electrons on the shells are Protons, therefore the other shaded sub-atomic particle are the Neutrons.
