Answer 2

Answer and Explanation:

• 11) 40 Nucleons are present in Calcium

                  mass number of Ca, A = 40

           the mass number is the sum of protons and neutrons which are   particles in the nucleus (nucleons), So it is equal to the  nucleon number.

Number of nucleons = number of protons + number of neutrons = A = 40

Thus Ca has 40 nucleons.

• 12) ion, cation, and anion

Ion is an electrically charged atom or molecule. A cation is a positively charged atom or molecule. An anion is a negatively charged atom or molecule.

• 13) symbols of ammonium and hydronium ions

                  ammonium ion - NH₄⁺

                  hydronium ion -  H₃O⁺
