Atomic number of a few elements are given below 10, 20, 7, 14
What would be the electronic configuration for each of these elements?

Explanation

To determine the electronic configuration of the elements with atomic numbers 10, 20, 7, and 14, we will follow the principles of electron filling in atomic shells. The shells are labeled K, L, M, N, etc., and they can hold a maximum number of electrons as follows:

- K shell (1st shell) can hold a maximum of 2 electrons.
- L shell (2nd shell) can hold a maximum of 8 electrons.
- M shell (3rd shell) can hold a maximum of 18 electrons, but we will follow the octet rule, which states that we fill up to 8 electrons in the M shell before moving to the N shell.
- N shell (4th shell) can also hold a maximum of 32 electrons.

Now, let's determine the electronic configurations for the given atomic numbers step by step.
