Question

k and l shell are full then what is its atomic number​

Answer 1

Answer:

Neon is the element with atomic number 10(2,8)

Answer 2

Answer: The atomic number is 10.

Explanation: The maximum number of electrons that can be occupied in K and L-shells of an atom are 2 and 8 respectively. Therefore, if K and L-shells of an atom are full, then the total number of electrons in the atom would be (2 + 8) = 10 electrons.

No of electron = no of proton = atomic no

so atomic no is 10 and the element neon.
