(a) Find to three significant digits the charge and the mass of an ionized hydrogen atom, represented as H+. Suggestion: Begin by looking up the mass of a neutral atom on the periodic table of the elements.
(b) Find the charge and the mass of Na+, a singly ionized sodium atom.
(c) Find the charge and the average mass of a chloride ion Cl− that joins with the Na+ to make one molecule of table salt.
(d) Find the charge and the mass of Ca++ = Ca2+, a doubly ionized calcium atom.
(e) You can model the center of an ammonia molecule as an N3− ion. Find its charge and mass.
(f) The plasma in a hot star contains quadruply ionized nitrogen atoms, N4+. Find their charge and mass.
(g) Find the charge and the mass of the nucleus of a nitrogen atom.
(h) Find the charge and the mass of the molecular ion H2O−.
