Draw all staggered and eclipsed conformations using Newman projections (looking down the C2-C3 bond) as well as line-and-wedged structures of 2-methylbutane. Determine the most stable and least stable conformations. Use the following chart to estimate the relative energies of each conformation.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
