Number of neutrons
It is the mass number take away protons
Number of electrons
Number of protons in a atom
What does the nucleus contain
The protons and neutrons
What is the things on the shell
The electrons
How many electrons can go on the first shell
2
How many electrons can go on the other shells
You can only have 8 on the other ones
What is isotypes
Its a atom of same element, different mass numbers, smae number of protons,different number of neutrons
What is a group number
A group number is the columns in the periodic table
What is a period number
A period number is the rows in the periodic table
Properties of an electron
Electrons spin on the axes like planets
Properties of a neutron
They are neutral particles which means they have no electric charge and they have no magnetic moment
Properties of a protons
Protons have less mass that neutrons in the nucleus but they are 1,836 more massive than electrons
