Question

Describe the characteristics of isotopes

Answer 1

Answer:

Isotopes are atoms of the same element with same number of electrons and protons but different number of neutron. Since they have different numbers of neutrons, this affects the mass number. Mass number determines the physical properties such as boiling/melting/density etc.

Explanation:

Answer 2

Explanation:

Isotopes are those elements which have the same atomic number but different mass number.

For examples the isotopes of hydrogen are promitium ( atomic number=1, mass number=1), deuterium ( atomic number =1, mass number=2) and tritium (atomic number=1, mass number=3).
