Answer : The correct option is 2.
Explanation :
Number of protons = 7
Number of neutrons = 6
Number of electrons = 10
Protons are those which carries positive charge.
Electrons are those which carries negative charge.
Neutrons are those which do not carry any charge that means neutrons are neutral.
The net charge on an ion = Number of protons present in an ion + Number of electrons present in an ion
The net charge on an ion = (+7) + (-10) = -3
Therefore, the net charge on an ion is (-3).
The eight-element periodicity found in the Periodic Table is related to the number of electrons in the outermost energy level of the atoms that make up each element
