How many electrons does a mn have in its 3d subshell?

Answer : The number of electrons present in 3d subshell of Mn are, 5 electrons.

Explanation :

Electronic configuration : It is defined as the representation of electrons around the nucleus of an atom.  

Number of electrons in an atom are determined by the electronic configuration.

The given element is 'Mn' that has 25 number of electrons.

The electronic configuration of Mn will be,

From the electronic configuration of 'Mn' we conclude that, there are 5 number of electrons present in 3d subshell of Mn.

Hence, number of electrons present in 3d subshell of Mn are, 5 electrons.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
