The three basic components of an atom are:(a) protons, neutrons, and ions(b) protons, neutrons, and electrons(c) protons, neutrinos, and ions(d) protium, deuterium, and tritiumAn element is determined by the number of:(a) atoms(b) electrons(c) neutrons(d) protonsThe nucleus of an atom consists of:(a) electrons(b) neutrons(c) protons and neutrons(d) protons, neutrons, and electronsA single proton has what electrical charge?(a) no charge(b) positive charge(c) negative charge(d) either a positive or negative chargeWhich particles have approximately the same size and mass as each other?(a) neutrons and electrons(b) electrons and protons(c) protons and neutrons(d) none - they are all very different in size and massWhich two particles would be attracted to each other?(a) electrons and neutrons(b) electrons and protons(c) protons and neutrons(d) all particles are attracted to each otherThe atomic number of an atom is:(a) the number of electrons(b) the number of neutrons(c) the number of pro tons(d) the number of protons plus the number of neutrons Changing the number of neutrons of an atom changes its:(a) isotope(b) element(c) ion(d) chargeWhen you change the number of electrons on an atom, you produce a different:(a) isotope(b) ion(c) element(d) atomic massAccording to atomic theory, electrons are usually found:(a) in the atomic nucleus(b) outside the nucleus, yet very near it because they are attracted to the protons(c) outside the nucleus and often far from it - most of an atoms volume is its electron cloud(d) either in the nucleus or around it - electrons are readily found anywhere in an atom Answers: 1 b, 2 d, 3 c, 4 b, 5 c, 6 b, 7 c, 8 a, 9 b, 10 c
