Answer 1

(2) (K) Atomic number = number of protons = 19 Element with 2=19, is potassium less number of electrons (18-19), indicates positive charge on atom. Answer: charge on ion + name of the element: Potassium Symbol for the ion Kt

number of electrons < number of protons indicates positive charge. charge = 19(+1) + 18(-1) = + Tinet p-charge to charge charge
