Explanation Total number of protons and atomic number is equal for an element Mass number is equal to the sum of number of neutrons and protons. In case of neutral atom, number of electrons is equal to the number of protons. For example: In 2 4 He , Atom Protons=atomic number Electrons = number of protons Mass number = protons + electrons He 2 2 4 When 1 electron is lost, the atom acquires positive charge and when 1 electron is gained, it acquires negative charge Formulae used: Atomic number = number of protons = number of electrons (for neutral atoms) Number of electrons lost = Atomic number − Electrons remaining Number of electrons gained = Total electrons after gaining − Atomic number Given: Potassium ( + 1 ) i.e. + 1 charge on it shows that it has lost 1 electron. Number of protons = 12 Number of electrons =10 Number of protons = 8 Number of electrons gained = 2 Number of electrons = 10 Electrons lost = 3 Calculations: Atomic number of potassium is: 19 Number of protons = atomic number = 19 Number of electrons after losing 1 electron = 19 − 1 = 18 e − As we
