- the first shell (the K shell) can only contain a maximum of two electrons, as it consists of just an s orbital
- the second shell (the L shell) can contain a maximum of eight electrons, as it consists of an s orbital and three p orbitals
- the third shell (the M shell) can contain a maximum of eighteen electrons, as it consists of an s orbital, three p orbitals, and five d orbitals
- the fourth shell (the N shell) can contain a maximum of thirty two electrons, as it consists of an s orbital, three p orbitals, five d orbitals, and seven f orbitals
- the fifth shell (the O shell) can contain a maximum of fifty electrons, as it consists of an s orbital, three p orbitals, five d orbitals, seven f orbitals, and nine g orbitals
- etc.
What else can I help you with?
What is the number of electrons that can occupy the first shell of an atom?
The first shell of an atom can hold a maximum of 2 electrons.
What is the maximum number of electrons in the second electron shell?
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.
Does Helium have 2 electrons in the first shell and 4 in the second?
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.
How many valence electrons are on the first 3 energy levels?
The first energy level has a maximum of two valence electrons. The second and third energy levels have a maximum of 8 valence electrons.
According to quantum mechanics what is the maximum number of electrons that can occupy the third energy level in a ground state atom?
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.
Why Two electron shells in oxygen?
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.
What is the maximum number of electrons in the first shell?
2 electrons are found in the first electron shell.
What is the number of electrons that can occupy the first shell of an atom?
The first shell of an atom can hold a maximum of 2 electrons.
What is the maximum number of electrons in the second electron shell?
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.
Does Helium have 2 electrons in the first shell and 4 in the second?
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.
What is the maximum number of electrons in the second principal energy level?
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.
How many electrons are required to fill the first shell?
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.
As many as four electrons can occupy the same orbitals?
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).
How many electrons can occupy a single molecular orbital?
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
What are the maximum number of electrons found in the first shell and second shell?
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 ? )
How many electrons at the maximum can be present in the first shell?
Two electrons can fit in the first shell
The first energy level of an atom can hold a maximum of how many electrons?
The first energy level of an atom can hold a maximum of 2 electrons.
