(a)
Interpretation:
Symbol of ion has to be written that has 4 protons, 2 electrons, and 5 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 32 protons, 30 electrons, and 40 neutrons.
Concept Introduction:
Refer part (a).
(c)
Interpretation:
Symbol of ion has to be written that has 35 protons, 36 electrons, and 44 neutrons.
Concept Introduction:
Refer part (a).
