Chemistry Question on Electronic Configurations Of Elements And The Periodic Table

The correct symbol of the species with number of electrons, protons and neutrons as 18,1618,16 and 1616 respectively is

A

1632S^{32}_{16}S

B

1832S^{32}_{18}S

C

1632S2−^{32}_{16}S^{2-}

D

1832S2−^{32}_{18}S^{2-}

Answer

1632S2−^{32}_{16}S^{2-}

Explanation

Solution

Number of protons = Atomic number = 1616
Thus, the element is sulphur
Further, mass number = number of protons + number of neutrons =16+16=32=16 + 16 = 32
Since, number of electrons are greater than the number of protons, so it must be an anion (i.e., obtained by accepting two electrons Hence, the correct symbol of the species must be 1632S2−^{32}_{16}S^{2-}
