The number of electrons, neutrons and protons in a species are equal to 10,8 and 8 respectively. The proper symbol of the species is

A

`""^(16)O_(8)`

B

`""^(18)O_(8)`

C

`""^(18)Ne_(10)`

D

`""^(16)O_(8)^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
D
From the given data, it is clear that the atomic no. Z, of the species is 8 (no. of protons). Since the no. of electrons are two more than the no. of protons, hence, it is a binegative species. Thus, the species is `""^(16)O_(8)^(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.
