Question

1- According to the modern atomic theory, ....

a) The electron cannot be found in the same place 2 successive times
b) The electrons need to absorb energy photons continuously to move to higher levels.
c) The electron transfer to a lower energy level when losing one quantum
d) No correct answer

Answer 1

According to the modern atomic theory, electrons need to continuously absorb energy photons to move to higher levels.

Step-by-step explanation:

According to the modern atomic theory, the correct answer is b) The electrons need to absorb energy photons continuously to move to higher levels.

In the modern atomic theory, the electrons in an atom exist in specific energy levels or orbitals around the nucleus. To move to a higher energy level, an electron must absorb a quantum of energy in the form of a photon. This energy is then used to move the electron to a higher orbital.

Option a) is incorrect because the electron can exist in the same place more than once, although it is subject to the Heisenberg uncertainty principle. Option c) about electron transfer to a lower energy level when losing one quantum is not accurate according to the modern atomic theory.
