Solution: Rank the elements Be, B, C, N, and O in order of increasing first ionization energy. Explain your reasoning.

Problem

Rank the elements Be, B, C, N, and O in order of increasing first ionization energy. Explain your reasoning.

Solution
  • Ionization energy is the energy required to remove an electron from a gaseous atom or ion. First ionization energy will be the energy required to remove the outermost electron 

  • Generally, the trend for ionization energy in the periodic table is that it increases as we go from left to right and increases also from bottom to top. 

  • Reason is as number of atomic number or proton increases, the positive charge in the nucleus increases which attracts the electrons making it hard to remove electrons
