Question

Identify the model of an atom. Which formula is used to calculate number of electrons in the orbit? How many electrons can be accomodated in 1st shell, 2nd shell , 3rd shell?

​

Answer 1

Answer:

maximum number of electrons present in a particular shell is calculated by the formula 2n2, where “n” represents the shell number. For instance, K shell is the first shell and it can hold up to 2(1)2 = 2 electrons. Similarly, L shell is the second shell and it can hold up to 2(2)2 = 8 electrons.
