Check the circled atoms in the attached diagram
Explanation:
The circled options all belongs to the same elements. They are simply isotopes.
Since:
Red ball = protons
Yellow ball = neutron
Blue ball = electron
The protons are positively charged and with the neutrally charged neutrons they both occupy the vicinity of the nucleus of an atom.
Electrons moves round the nucleus in orbits.
Atoms of the same elements have the same number of protons.
The circled options all have two protons.
The atoms only differ in the number of neutrons which signifies that they are merely isotopes.
More descriptively, the atoms are Helium atoms.
