Question

In order for an electron to move from the second energy level (n=2) to the fourth energy level (n=4) the atom needs to :

• A. release heat.
• B. release a photon.
• C. maintain a constant energy.
• D. release energy.
• E. absorb energy.

Answer 1

Answer: (E)

absorb energy.

Lower level (n=2) is lower energy level whereas the higher level (n=4) is the higher energy level hence the energy is required to abosorb to jump the electron from n =2 to n = 4.
