Question

An atom has 1 proton,0 neutrons,and 1 electron; its isotope has:
A) 2 electrons and 0 neutrons.
B) 2 protons and 2 neutrons.
C) 1 proton and 1 neutron.
D) 2 protons and 0 neutrons.

Accepted Answer

Isotopes of an element have the same number of protons but different numbers of neutrons. Since the original atom has 1 proton and 0 neutrons, its isotope with 1 proton and 1 neutron fits the definition.
