- 1What is the relative mass, relative charge and location in the atom of a Proton ?1 , + 1 , nucleus
- 2What is the relative mass, relative charge and location in the atom of a Neutron ?1 , 0 , nucleus
- 3What is the relative mass, relative charge and location in the atom of a Electron ?1 / 1840 , - 1 , energy levels
- 4What is the 'atomic number' equal to ?The atomic number is equal to the number of protons in the nucleus of an atom.
- 5What is the 'mass number' a total number of ?The mass number is the total number of protons and neutrons in the nucleus of an atom.
- 6What are 'isotopes' ?Atoms of the same element, which have a different mass numbers, are called isotopes.
- 7What does all the isotopes of an element have the same number of ? Why is this?All the isotopes of an element have the same atomic number.
As they have the same number of protons in the nucleus. - 8What is the formulae to work out the mass number ?Mass Number = Number of protons + Number of Neutrons
- 9What is the formulae to work out the atomic number ?Atomic Number = Number of protons
- 10What is the formulae to work out the number of neutrons ?Number of Neutrons = Mass number - Atomic number
- 11What is the formulae to work out the number of electrons ?Number of Electrons = Number of protons [in a neutral atom]
