Answer 1

1- Bohr's model shows the electron circling the nucleus in the fixed orbit. CORRECT,as according to Bohr's model the electrons in an atom are fixed to specific orbits around the nucleus of the atom.

2- In Bohr's model the electron could exist in between orbits, INCORRECT, because in Bohr's model, the electrons in an atom are fixed to specific orbits around the nucleus of the atom and they have descrete energies i.e the energies of the electrons are quantized , hence they cannot exist in between orbits.

3- In Bohr's model when an electron absorbs energy it moves higher the orbits. CORRECT, as when electron absorbs energy it get exited and jumps to a higher energy orbit due to increased energy of the electron.

4- In Bohr's model when an electron emits energy it moves lower the orbits. CORRECT, as when electron emits energy it losses and jumps to a lower energy orbit due to decreased energy of the electron.

5- n=1 is the lowest energy level,CORRECT ,because at n=0 the energy for the level should also be zero but it is not zero but infinity,hence the minimum energy found at n=1 hence n=1 is known as the lowest energy level.
