Interpretation:
The total number of protons, neutrons, and electrons and the mass number of each isotope of argon is to be determined.
Concept introduction:
Isotopes are the different forms of an element which occupy the same position in the periodic table and have the same
The mass number of an atom is the sum total of the number of protons and neutrons in the nucleus of the atom. The general representation for an atom is given as
An electron is a negatively charged sub-atomic particle that revolves around the nucleus within an atom.
Protons and neutrons comprise the nucleus of an atom. The nucleus of an atom is positively charged. While the protons are positively charged, the neutrons are neutral. Hence the positive charge of an atomic nucleus is due to the presence of the positively charged protons in it.
