Absorbed energy is said to be quantized. This means:____________ a) Energy is absorbed only by valence electrons. b) Energy caus
wlad13 [49]

Answer:Energy is absorbed in exact amounts that correspond to differences in energy levels.

Explanation:

According to Bohr's theory, an electron moves from a lower to a higher energy level when it absorbed photon of a given energy. The energy of the photon absorbed must be equal to the energy difference between the higher and lower energy level. Thus energy is absorbed only in discreet amounts that correspond to differences in energy levels. Absorption of energy in discreet amounts is what is meant by the term 'quantization'.
