Get started for free(a) In what unique way did Mendeleev order the elements to make his discovery? (b) What was his discovery? (c) How does his ordering differ from the modern ordering?
For each pair, indicate which atom loses an electron more easily: (a) \(\mathrm{Na}\) or \(\mathrm{K}\) (b) Na or Al (c) \(\mathrm{Rb}\) or \(\mathrm{Ca}\) (d) \(\mathrm{S}\) or \(\mathrm{Cl}\) (e) Br or Kr
Atom A has 35 protons and 44 neutrons in its nucleus. Atom \(\mathrm{B}\) has 35 protons and 46 neutrons in its nucleus. Should we expect similar or different chemical properties for these atoms? Explain.
It always takes energy to remove an electron from a neutral atom. Explain why, and name the minimum amount of energy it takes to do this.
In Rutherford's alpha-particle scattering experiment: (a) How did he interpret the observation that only a very few of the \(\alpha\) particles were scattered by the gold foil and most of them went straight through? (b) What was wrong with his model of the atom as far as the physics of the day was concerned?
