Elements with _ first ionization energies and _ electron affinities generally form cations.
Correct answer: C. low, positive or slightly negative
- A. low, very negative
- B. high, positive or slightly negative
- C. low, positive or slightly negative
- D. high, very negative
Explanation
The correct option is:c. low, positive or slightly negativeElements with low first ionization energies are more likely to lose electrons easily. First ionization energy is the energy required to remove the outermost electron from an atom.Elements with low electron affinities are less likely to gain electrons. Electron affinity is the energy change associated with gaining an electron.Cations are formed when an atom loses electrons. Therefore, elements with low first ionization energies and positive or slightly negative electron affinities are more likely to form cations. These elements are more inclined to lose electrons than gain them.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
