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.

<span>5 electrons
</span>The electron configuration of an atom shows or describes the distribution of electrons in their atomic orbitals. In particular, it shows the distribution in terms of the principal energy levels or electron shells (reflected by the numbers 1, 2, 3, 4, 5, 6, 7) and their corresponding subshells (reflected by the letters s,p,d,f,g) composed of atomic orbitals.
The maximum number of electrons in the s-subshell is 2, in the p-subshell, 6, in the d-subshell, 10, in the f-subshell, 14, and in the g-subshell, 18. In the electron configuration of an atom, the number of electrons in the subshell for a given atom is reflected by a number (in superscript) next to the corresponding letter of the subshell.
<span>The electron configuration of a chlorine atom in its ground state is
</span>
Thus, the number of electrons in the 3rd energy level in the p-subshell is 5 (
as seen in the electron configuration of the atom).
