The atomic number of the atom which becomes stable by gaining 3 electrons in 5th shell is :
Open in App
Solution
The correct option is D 51
The element Sb with atomic number 51, has electronic configuration 2, 8, 18, 18, 5.. Thus with addition of 3 electrons the outer valence shell will complete its octet hence becomes stable.
Hence, the correct option is C
