(a)
Interpretation:
Symbol of ion has to be written that has 8 protons, 10 electrons, and 8 neutrons.
Concept Introduction:
Each and every element present in the Periodic table has a unique name. Some of the elements are named considering their
Chemical names are represented as atomic symbols. In the symbols, the mass number and atomic number are shown. The complete
Atomic number is the total number of protons present in the atom of an element. Mass number is the total number of protons and neutrons present in nucleus of an atom.
(b)
Interpretation:
Symbol of ion has to be written that has 34 protons, 36 electrons, and 45 neutrons.
Concept Introduction:
Refer part (a).
(c)
Interpretation:
Symbol of ion has to be written that has 28 protons, 26 electrons, and 31 neutrons.
