Question

How many electrons are present in this element?​

Answer 1

Answer:

The atomic number of an element is 20. Atomic number is equal to the number of electrons present in a neutral atom. Thus, the element with atomic number 20 has 20 electrons. Out of 20 electrons, 2 electrons are present in the K-shell and 8 electrons are present in the L-shell

• ✿ There are total 11 electrons in the above atom.

${\bold{\underline{\underline{\tt{\color{purple}{ꜱᴛᴇᴘ- ʙʏ-ꜱᴛᴇᴘ \: \: ɪɴꜱᴛʀᴜᴄᴛɪᴏɴꜱ :-}}}}}}$

• ► K shell = 2 electrons
• ► L shell = 8 electrons
• ► M shell = 1 electrons

=> Total electrons = (2 + 8 + 1)

=> 11 electrons
