The first shell of an atom can hold 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.
No, Helium has 2 electrons in total, both of which occupy the first electron shell. The first electron shell can hold a maximum of 2 electrons, so Helium's electron configuration is 2.
The first energy level has a maximum of two valence electrons. The second and third energy levels have a maximum of 8 valence electrons.
The first level can hold 2, the second can hold 8, and the third can hold 18 electrons. However, the outer level never holds more than 8; therefore an atom containing only 3 levels will have only 8 in the 3rd level.
Oxygen has two electron shells because it has eight electrons. The first shell can hold a maximum of two electrons, while the second shell can hold up to eight electrons. In oxygen, two electrons occupy the first shell and the remaining six electrons occupy the second shell to satisfy the octet rule.
2 electrons are found in the first electron shell.

The maximum number of electrons in the second principle energy level (n=2) is 8. This can be determined from 2(n^2) which for n=2 would be 2 x 4 = 8. It can also be seen by writing the electron configuration for n=2 which would be 2s2 2p6 for a total of 8 electrons.
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.
No. Electrons are fermions, meaning they cannot share the same set of four quantum numbers. Usually when we say "orbital" we only mean the first three, so there is room for two electrons in an orbital (corresponding to the two possible ms values).
Every orbital is different. 2 can occupy the first orbital then 8 can occupy mostly the rest. When you start getting really low on the periodic table orbitals start holding 16, but not till u get really low
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 ? )
Two electrons can fit in the first shell
The first energy level of an atom can hold a maximum of 2 electrons.
