Question

A weak atom has 2 electrons in cell K, four in cell L, two electrons in cell M. Remove atomic number of element. Write the signal of the ion generated after removing 2 electrons from the M cell of the atom of the element.​

Answer 1

Answer:

K L M

2 8 8

Thus, atomic number of the element will be 18.

And electronic configuration of the element can be given as:

1s2 2s2 2p6 3s2 3p6

Thus, total number of s electron is 6.
