2 electrons are found in the first electron shell.
The maximum number of electrons in the first energy shell of an atom is 2. This limitation is due to the shell's capacity to accommodate a maximum of one s orbital, which can hold a maximum of two electrons, each with opposite spins.
First orbital can be occupied by a total of 2 electrons and the second orbital can be occupied by a total of 8 electrons. 1s^2 2s^2 2p^6 ( what element is this ? )

by knowing the no. of electorns in its outermost shell
The first shell of an atom can hold a maximum of 2 electrons. Since the number of protons in an atom is equal to the number of electrons in a neutral atom, there can be a maximum of 2 protons in the first shell.
The least number of electrons needed in a shell is 2, as the first shell can hold a maximum of 2 electrons.
The first shell can hold two electrons only.
Well the formula for calculating the maximum amount of electrons that can be held in a shell of an atom is: 2(n)2 N being the shell number. For example: 2(1)2= 2 (the maximum amount of electrons for shell number 1)
The number of electrons in a shell is 2n2, where n=shell number. So for the first shell, there is a maximum of 2 electrons.
8 (just in the second shell) but if you're counting all of the electrons, including the first shell, then there are 10 electrons all together. Eight Electrons are the maximum.
A nucleus can have up to seven shells and the maximum each shell can hold is 2N^2. The maximum number of electrons found in any shell of known elements is 32.
