How can you work out the number of neutrons in an atom?
It is the same as the atomic number
It is the same as the atomic mass
It is the atomic mass minus the atomic number
It is the atomic number minus the atomic mass
Which subatomic particle is responsible for chemical properties such as bonding?
Electron
Proton
Neutron
Isotopes are atoms of the same element with a different mass. This means the same chemical properties but different physical properties.
Isotopes of an element have the same number of:
Protons and neutrons
Neutrons and electrons
Electrons and protons
Protons, neutrons and electrons
