Question

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

Answer 1

Answer:

proton is equal to atomic no. means the atomic no. of the element is 16...that is sulphur now two more electrons are added to sulphur...ie.it becomes. S2-

Explanation:

hope it helps...plz mark it as brainliest and try to follow me

Answer 2

The atomic number is equal to number of protons = 16

• The element is sulphur (S)

Atomic mass number = number of protons + number of neutrons

• 16 + 16
• 32

$\rightarrow$Species is not neutral as the number of protons is not equal to electrons.

$\rightarrow$It is anion with charge equal to excess electrons = 18 - 16 = 2

$\rightarrow$ $^{32}_{16}$S$^{2-}$ (Symbol)
