QUESTION 1 Which of the following statements is the assumption that Bohr made about the angular momentum of the electron in the hydrogen atom? O The angular momentum can assume only certain discrete values The angular momentum of the electron is zero Angular momentum is not quantized. The angular momentum can assume any value greater than zero because it is proportional the radius of the orbit QUESTION 2 Each atom in the periodic table has a unique set of spectral lines. Which of the following statements is the best explanation for this observation? Each atom is composed of positive and negative charges Each atom has a dense central nucleus. O Each atom has a unique set of energy levels The electrons in atoms orbit the nucleus. The electrons in atoms are in constant motion.

Explanation / Answer

Question Number 5 is wrong:

The answer is only 4, 5 , 6, 7 or 8

as ml values changes from -l to +l.

Question number 3:

It predicts the angular momentum and the energy.
