Which model of the atom states that electrons are located in set orbits around the nucleus?
a. dalton’s
c. bohr’s
b. rutherford’s
d. the modern

Answer : Bohr's states that electrons are located in set orbits around the nucleus.

Explanation :

According to the first postulate of Bohr, the electrons are located in set orbits around the nucleus. The orbits are denoted by some alphabets like K, L, M, N and so on.

These orbits are known as stationary orbits or stationary states.

According to his second postulate, the angular momentum of an electron is given by where n is integers and h is Planck's constant.

He also postulated that, if an electron makes a jump from higher to the lower orbit then energy is released in the form of radiation.

While if it jumps from lower to higher orbit it absorbs energy in the form of radiation.

So, the correct option is (C) "Bohr's".
