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

Text Solution

Verified by Experts

Atomic number is equal to number of protons = 16
So, the element is sulphur (S)
Mass number = No. of protons + No of neutrons
`=16 + 16 = 32`
Species is not neutral because the number of protons is not equal to number of electrons. It is anion with charge equal to excess electrons = `18 - 16 = 2`
`:. "Symbol is" ""_16^32(S)^(2-)` .

The numbers of electrons, protons, and neutrons in a species are equal to 18,16 , and 16 , respectively. Write the symol for the species in the standard format. Strategy: Before usding the standard notation _(Z)^(A)X , find out wheter the species is a neutral atom, a cation, or an anion. if it is a neutral atom, Eq is valid, i.e. Number of protons = Number of electrons = Atomic number If the species is an ion, determine whether the number of protons is larger (cation, a positive ion) or smaller (anion, a negative ion) than the number of electrons. Number of neurtons is always given by Eq. i.e., N=A-Z , whether the species is neutral or charged.
