You are watching: Consider the n = 3 energy level in a hydrogen atom. how many electrons can be placed in this level?
Consequently, how many electrons can n 3 have?
Beside above, how many electrons in an atom can have n 3 and L 2? Therefore, a maximum number of 10 electrons can share these two quantum numbers in an atom. These electrons are located on the third energy level, in the 3d subshell.
Also, how many Subshells are in the N 3 level?
How many electrons can have the quantum numbers n 3 and L 2?
The maximum number of electrons with quantum numbers with n=3 and l=2 is 10 .
Hence total 6 electrons can fit for n=3 and l=1 If the value of third shell is 3 or n=3 with sub-shell value l=1. This means each orbital will contain two electrons. There exist three p orbitals. Each electron will combine with three orbitals; finally, you will find six electrons will fit into the orbit.
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
A subshell is a subdivision of electron shells separated by electron orbitals. Subshells are labelled s, p, d, and f in an electron configuration.
The principal quantum number, n, describes the energy of an electron and the most probable distance of the electron from the nucleus. In other words, it refers to the size of the orbital and the energy level an electron is placed in. The number of subshells, or l, describes the shape of the orbital.
This first shell has only one subshell (labeled 1s) and can hold a maximum of 2 electrons. This is why there are two elements in the first row of the periodic table (H & He). Because the first shell can only hold a maximum of 2 electrons, the third electron must go into the second shell.
s, p, d, f and so on are the names given to the orbitals that hold the electrons in atoms. These orbitals have different shapes (e.g. electron density distributions in space) and energies (e.g. a hydrogen atom with one electron would be denoted as 1s1 - it has one electron in its 1s orbital.
Thus, the first shell (n = 1) consists of only one subshell, the ls (l = 0); the second shell (n = 2) consists of two subshells, the 2s (l = 0) and 2p (l = 1); the third shell consists of three subshells, 3s, 3p, and 3d, and so forth. Each subshell consists of a specific number of orbitals.
For any given shell the number of subshells can be found by l = n -1. This means that for n = 1, the first shell, there is only l = 1-1 = 0 subshells. ie. the shell and subshell are identical.
