1
Q
What are isotopes?
A
Atoms of the same element which have the same number of protons but different number of neutrons
2
Q
What does a different mass number mean?
A
Different number of neutrons
3
Q
Why do isotopes of an element have the same chemical properties?
A
They have the same configuration of electrons
4
Q
Why do isotopes of an element have slightly different physical properties?
A
Physical properties (e.g. density, rates of diffusion) depend on the mass of the atom
