Why does M shell have 8 electrons?

The maximum capacity of a shell to hold electrons is 8. The shells of an atom cannot accommodate more than 8 electrons, even if it has a capacity to accommodate more electrons. This is a very important rule called the Octet rule.

How many orbitals are present in the M shell?

Which is the best definition of the word shell?

Where does the name mine shell come from?

The name ‘mine shell’ is in English a modern term directly translated from the German military term minengeschoß. The historical equivalent English military term is High-Explosive, High-Capacity, abbreviated as HEHC, which has become uncommon or obsolete in modern times.

How big is a high explosive mine shell?

To the left is a 25 cm mine shell; to the right a 24 cm high-explosive shell. The mine shell is a more explosive version of the common high-explosive and high-explosive fragmentation shells, relying on inflicting damage primarily through the blast rather than via the combination of penetration, blast and fragmentation achieved by normal ammunition.

What is the purpose of a mine shell?

Originally used to attack fortifications, it is today mainly used against aircraft, both in ground-based and airborne weaponry.
