Question

In general, electrons far from the nucleus have more potential (chemical) energy than electrons closer to the nucleus in the same atom.

	True
	False

Expert Solution

Step 1

The lowest energy would be in electrons nearest to the nucleus. Higher energy will be provided to electrons further away from the nucleus. The electron shell of an atom can accommodate 2n2 electrons (where n is the shell level). In a more practical model, in atomic orbitals, or subshells, electrons pass.

Polonium is a rare element with 33 radioisotopes. The most common one, P210o, has 84 protons and 126 neutrons. When P210o decays, it emits an alpha particle, which is a helium nucleus 2 protons and 2 neutrons. P210o decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason why authorities failed to discover toxic amounts of P210o in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of P210o change into after it emits an alpha particle.
