2) pick the statement about the bohr model of the hydrogen atom that is not true. a) the energy of each bohr orbit is quantized. b) an electron in a stationary state does not emit radiation. c) when an electron jumps to a higher state, energy is absorbed. d) when an electron jumps from one state to another, the electron must gain or lose just the right amount of energy to actually travel the distance between the orbits.

When an electron jumps from one state to another, the electron must gain or lose just the right amount of energy to actually travel the distance between the orbits.

Explanation:

Bohr in his structure of atom explained that protons which are positively charged particles and neutrons which are neutral particles,  are contained in the center of an atom called as nucleus.

The electrons which are negatively charged particles revolve around the nucleus in fixed orbit or shell or energy levels which are termed as quantized. These energy levels are stable and are stationary along with different energy value.  The electron remains in the state until energy is absorbed or released.

The electrons absorb energy when it moves from lower energy state to higher energy state. The electrons lose energy when it moves from higher energy state to lower energy state and thus emit radiations corresponding to the energy gap.

Thus the statement  when an electron jumps from one state to another, the electron must gain or lose just the right amount of energy to actually travel the distance between the orbits is incorrect because energy is absorbed when electron jumps from one state to another.

The energy is lost when electron falls from one state to another.

the awnser is group 12

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
