Question

In which subshell of the outermost shell electrons are present magnesium 2,8,2?​

Answer 1

Answer:

m

Explanation:

first shell is k it's copleted full

and m is also full .

so magnesium is present in n shell

Answer 2

3s subshell.

3s subshell of the outermost shell electrons are present magnesium 2,8,2

• Alkaline earth metal magnesium is a member of group IIA on the periodic table. It has two valence electrons in the 3s subshell.
• An atom can only have a certain amount of electrons in each of its shells: the first shell can store up to two electrons, the second shell up to eight (2 + 6) electrons, the third shell up to 18 (2 + 6 + 10) electrons, and so on.
• The valence shell, which is the outermost occupied shell (or shells), contains the electrons that are responsible for the atom's chemical composition.
• An atom's valence shell is its outermost shell. Valence electrons are the electrons found in this shell. The valence electrons are responsible for carrying out chemical reactions and determining the atom's chemical composition. These are the atom's most loosely bound electrons since they are the furthest away from the nucleus.
• The valence shell is an atom's outermost shell when it is uncombined. It houses the electrons that are most likely to determine how the atom reacts and interacts with other atoms through bonds. It is important to keep in mind that the ion's outermost shell is not usually referred to as its valence shell.
