The number of electrons in the lowest electron shellis
2 in the first or K shell (subshell 1s)
---
For other shells, the maximum is determined by the formula 2n2:
2) 8 in the L shell (subshells 2s, 2p)
3) 18 in the M shell (subshells 3s, 3p, 3d)
4) 32 in the N shell (subshells 4s, 4p, 4d, 4f)
5) 50 in the O shell (subshells 5s, 5p, 5d, 5f, 5g*)
6) 72 in the P shell (subshells 6s, 6p, 6d, 6f, 6g, and an unnamed subshell)
7) 98 in the Q shell (subshells 7s, 7p, 7d, 7f, 7g, and two unnamed subshells)
* the highest existing subshells are 5f, 6d, and 7s
* the highest currently predicted subshells are 7p and 8s
* no existing element has more than 32 electrons in any shell
The maximum per subshell is determined by the formula 2(2L+1) (s is 0):
s subshells can have 2 electrons
p subshells can have 6 electrons
d subshells can have 10 electrons
f subshells can have 14 electrons
g subshells can have 18 electrons
*There are no elements with electrons past the f subshell, so the shells with 22 and 26 electrons have no name. The largest element created (Roentgenium, element 111) has 2 electrons in the 7s shell.

What is the number of electrons in the 1st energy level of magnesium?
All elements except hydrogen have two electrons in the first energy level.
What is the electron configuration of an element?
The electron configuration of an element shows the number of electrons in their energy levels and orbitals. For example, the electron configuration of a neutral magnesium atom, Mg, with 12 electrons, is 1s22s22p63s2. This means that there are two electrons in the s orbital of the first energy level, two electrons in the s orbital and six electrons in the p orbital of the second energy level, and two electrons in the s orbital of the third energy level. The number in front of each letter represents the energy level, the letter represents the orbital, and the superscripts represent the number of electrons in the orbital.
How many electrons can go in the first second and third shell of an atom?
The first shell can hold a maximum of 2 electrons, the second shell can hold up to 8 while the third shell can also hold a maximum of 8.
How can an atom that has seven valence electrons complete its outermost level?
Look at the first element on the periodic table. The first energy level holds only two electrons, so Helium has filled its outer energy level. Atoms with an outer energy level that is not fill will fill it up by bonding with other atoms and sharing electrons.
What is a orbit in a atom?
http://www.answers.com/topic/atomic-orbital Atomic orbitals are cloud like structures around the nucleus of an atom that contain the atoms electrons. There are s, p, d, and f orbitals. S contain up to 2 electrons, P contain up to 6 electrons, d contain up to 10 electrons, and f contain up to 14 electrons. These orbitals have electrons containing different amounts of energy, and it is possible for electrons to jump to and from different orbitals. When this happen energy either needs to be added or released. The number of orbitals present in an atom is completely dependent on the number of electrons present in the atom.
What is the maximum number of electrons that can fit in an atom's first energy level?
2 electrons
What is the maxium number of electrons an element can have on the first inner level?
The maximum number of electrons that can be found in the first energy level (or inner level) of an element is 2 electrons. This is because the first energy level only has one subshell, which can accommodate a maximum of 2 electrons.
Maximum number of electrons in each energy level?
The maximum number of electrons in each energy level is determined by the formula 2n^2, where n represents the energy level (shell). For example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold a maximum of 8 electrons, and so on.
What is the maximum number of electrons an element with two energy levels can have?
An element with two energy levels can have a maximum of 8 electrons. The first energy level can hold up to 2 electrons, while the second energy level can hold up to 6 electrons.
How many electrons can be held in the energy level?
The maximum number of electrons that can be held in an energy level is given by the 2n^2 rule, where n is the principal quantum number of the energy level. So, for example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold a maximum of 8 electrons, and so on.
What the maximum number of electron can go in the first three energy levels subatomic particles?

How many electrons can be found in each of the first three energy?
The first energy level can contain 2 electrons. The second energy level can contain 8 electrons. The third energy level can contain 18 electrons.
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.
What is the maximum number of electrons in the first shell?
2 electrons are found in the first electron 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.
How many electrons dose each energy levels have?
The number of electrons in each energy level is determined by the formula 2n², where "n" is the principal quantum number of the energy level. For example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold a maximum of 8 electrons, and so on.
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.
