Interpretation:
The number of electrons, completely filled orbitals and number of orbitals with n=4 in Arsenic atom needs to be determined.
Concept introduction:
Electrons are placed in certain energy levels which are called as shell. The outermost shell of an atom is called as valence shell and the electrons are called as valence shell electrons. These valence shell electrons take part in all
Answer to Problem 91A
Number of electrons = 33
Number of completely filled orbitals = 10
In 4th shell there are total 4 orbitals in 4s and 4p.
Explanation of Solution
Given information:
Arsenic atom has n = 4 principal energy level.
Since in an atom, the
The electronic configuration of arsenic will be:
There are total 6 sub-shells are completely filled:
- 1s = 1 orbital
- 2s = 1 orbital
- 2p = 3 orbitals
- 3s = 1 orbital
- 3p = 3 orbitals
- 4s = 1 orbital
- Total = 10 orbitals
In 4th shell there are total 4 orbitals in 4s and 4p.
Number of electrons = 33
Number of completely filled orbitals = 10
In 4th shell there are total 4 orbitals in 4s and 4p.
