Isotopes of an element have - JAMB Chemistry 2023 Question
Isotopes of an element have
A
The same number of protons but different/same numbers of neutrons.
B
The same number of neutrons and electrons
C
The same number of protons and neutrons
D
The same number of protons and electrons
correct option: a
The same number of protons but different/same numbers of neutrons.
Isotopes of an element have the same number of protons (which defines the element) but different numbers of neutrons.
This results in isotopes having different atomic masses. The number of protons in an atom determines its element and chemical properties, while the number of neutrons can vary among isotopes of the same element. Isotopes of an element share the same number of electrons, ensuring they have the same chemical behaviour.
