Question

In an atom, M shell is the outermost shell, therefore it can have maximum of 8 electrons.

• A. True
• B. False

Answer 1

The correct option is A True

• The electronic configuration of an element refers to the arrangement of electrons in the various shells (or energy levels) of an atom.
• In other terms, the distribution of electrons in various shells (or energy levels) of an atom, such as the K shell, L shell, M shell, and so on, is known as electronic configuration.
• Although the maximum electrons a shell can accommodate are calculated using the formula$2{\mathrm{n}}^2$. According to this, M-shell can have a maximum of 18 electrons.
• Even if it has the capacity to have additional electrons, an atom's outermost shell cannot have more than 8 electrons.
• Hence, if in an atom, the outermost shell is M-shell, it can accommodate a maximum of 8 electrons.
• For example - Sulphur having atomic number 16 - Its electronic configuration is 2, 8, 6.
• Hence, the given statement is True.
