Bohr's Model of an Atom
Bohr's Model of the atom included idea(s) like:
Electrons in atoms, orbit the nucleus
The electrons can only revolve in certain orbits at certain distance from the nucleus
When electrons gain and lose energy they jump from one orbit to another
All of these.
Match the correct order of elements to corresponding to the atomic structure.
C, F, E, B, A, D
C, E, F, A, B, D
E, F, C, A, D, B
C, F, E, D, B, A
According to Bohr and Bury models, the electrons are not accommodated in a given shell, unless the inner shells are filled.
(c) Z + A
(d) Z - A
Select the correct statement that is proposed by Neils Bohr regarding the model of an atom.
The electron can have only certain energies, including a lowest-level ground state
All of these
Electrons emit energy as light when they move to lower energy orbits
Electrons absorb energy by moving to higher energy orbits.
- Cannot be predicted
- J.J. Thomson
- John Dalton
- Neil Bohr
Assertion: K, L, M, N orbits can accommodate maximum of 2, 8, 18, 32 electrons respectively.
Reason: The maximum number of electrons in particular orbit is given by 2n2, where n is orbit or shell number.
- Assertion is true, but reason is false.
- Assertion is false, but reason is true.
- Both assertion and reason are true.
- Both assertion and reason are false.
