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.

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.

The no of electrons, protons and neutron in a species are equal to 10,11,12 respectively. Assign proper symbol to the species.
