Which element has the most favorable (most negative) electron affinity? a. mg b. ne c. o d. na?

Identify which properties could correspond to solids, plasmas, or both. maintain a unique shape. collide infrequently with other particles. have very high velocities. conduct electricity. protons. have a low temperature. has long-range order.

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

Calculate the energy required to ionize a hydrogen atom to an excited state where the electron is initially in the n = 5 energy level. report your answer in kilojoules
