Question

The number of electrons, protons and neutrons in a species are equal to 18, 16 and 16 respectively. Assign the proper symbol to the species.​

Answer 1

Answer:

the symbol of the species is S²⁻

Explanation:

number of electrons = 18

number of protons = 16

number of neutrons = 16

Atomic Number, Z = number of protons = 16

Mass Number, A = number of protons + number of neutrons = 16 + 16 = 32

the neutral atom has an equal number of protons and electrons. Here atoms 2 more electrons, so the species is an anion with a charge of -2.

From the periodic table, the element with atomic number 16 is S (sulfur).

Then the required answer is S²⁻ ion
