How do you know how many electrons need to go in the second shell?
The formula is 2n2 where n is the principal quantum number (the "shell" number). In this case the second shell has a principal quantum number of 2 so 2X 22 = 8
What is a principal quantam number?
The principal quantum number (n) defines the main energy level or shell of an electron in an atom. It determines the average distance of the electron from the nucleus, as well as the energy of the electron. The higher the principal quantum number, the higher the energy level and the greater the distance from the nucleus.
How do you find valence shell?
The valence shell of an atom is the outermost shell that contains electrons. To find the valence shell, look for the highest number in the electron configuration or the number of the highest principal quantum level.
How can calculate electrons in N shell?
The number of electrons that can be accommodated in an "N" shell is given by the formula 2n^2, where "n" is the principal quantum number of the shell. For example, in the third shell (n=3), the number of electrons that can be accommodated is 2(3)^2 = 18 electrons.
How many valence electrons will calcium gain or lose to fill its outer shell?
A calcium atom will normally lose its two valence electrons, which have principal quantum number 4, to a more electronegative atom when forming a compound. When this happens, the already filled electron shell with principal quantum number 3 becomes the outer shell of the resulting calcium cation, and this cation has the electronic structure of the noble gas preceding calcium in the periodic table, neon

How many subshells present in principal energy shell?
The number of subshells present in a principal energy shell is equivalent to the principal quantum number. For example, in the first principal energy shell (n=1), there is only one subshell (s). In the second principal energy shell (n=2), there are two subshells (s and p), and so on.
What is shell?
Orbitals with the same value of Principal Quantum number , n.
How many electrons are in the fourth principal shell of a cadmium atom?
The fourth principal shell (n=4) can hold a maximum of 32 electrons. Cadmium has an atomic number of 48, so it has 48 electrons distributed across various energy levels/shells. Therefore, in the fourth principal shell of a cadmium atom, there are 32 electrons.
All of the orbitals in a given electron shell have the same value of the?
The same value of the principal quantum number.
How many electrons are required to fill the first shell?
The first shell can hold a maximum of 2 electrons.
Sodium has how many electrons in its outermost principal energy level?
Sodium has one electron in its outermost principal energy level, also known as the valence shell.

The total number of electrons inan electron shell is reepresented by the formula 2n . is this correc?
No, that is not correct. The total number of electrons in an electron shell is given by 2n^2, where n is the principal quantum number.
How can calculate electrons in N shell?
The number of electrons that can be accommodated in an "N" shell is given by the formula 2n^2, where "n" is the principal quantum number of the shell. For example, in the third shell (n=3), the number of electrons that can be accommodated is 2(3)^2 = 18 electrons.
