Answer Happy

The first ionization energy of oxygen is higher than that of
carbon. choose the one answer that properly justifies the
fundamental cause of this observation.
The first ionization energy of oxygen is higher than that of carbon Choose the one answer that properly justifies the fundamental cause of this observation O a Both are in the same period, but oxygen is more Electronegative than carbon. That means it attracts the electrons shared in covalent bonds with more strength, honoe more energy is required to remove them, Ob. Both are in the same period, but oxygen has a lower nuclear effective charge than carbon. That means its electrons are more loosely attracted to its nucleus, hence more energy is required to remove them O G Both are in the same period, but oxygen has a higher nuclear effective charge than carbon. That means its electrons are more loosely attracted to its nuclous, hence more energy is required to remove them Od Both are in the same period, but oxygen has a higher nuclear effective charge than carbon. That means its olactions are more strongly attracted to its nucleus, hence more energy is required to romove them O. Both are in the same period, but cygen has a lower nuclear effective charge than carbon. That means its electrons are more strongly attracted to its nucleus, hence more energy is required to remove them
