the fourmula is 2n square n= # of shells
The value of 'n' for the valence shells is the number of shells that specific atom has
The outer shell (N=4) of the copper element has 2 electrons.
Oxygen has 8 electrons in total. The distribution of these electrons in shells KLMN is as follows: K shell has 2 electrons, L shell has 6 electrons, M shell has 0 electrons, and N shell has 0 electrons.
The largest atom is calcium which has 4 shells.
The number of electrons in any given shell can be represented by 2n2, where n = the shell number. The first shell has 2, second has 8, third has 18...
No. N has 2 shells. N has an electronic configuration of 1s2 2s2 2p3 N is in period 2 of the periodic table which cooresponds to the filling left to right of the second energy shell.
A break down of 2d1:2 = the quantum energy level or electron shell denoted as 'n'd = the sub-shell of the energy level (known as a degenerate level)1 = the number of electrons occupying the sub-shell.Through extensive research by scientists, no known element has a d sub-shell in the second (n=2) energy level. In fact, the d sub-shell does not appear until the fourth period (fourth row).The first d sub-shell is known to be in the third energy level (therefore the first energy level with this sub-shell is 3d, but not 2d).Transition metals are the elements known to fill the d sub-shells. The first transition metal in the periodic table is scandium (Sc) with the electron configuration of [Ar]4s23d1.The reasons for the formation of sub-shell of d is beyond my knowledge and the scope of basic chemistry.
Each shell has a total of n2 orbitals, where n is the principal quantum number. For N shells the total orbitals is therefore :- N2 + (N-1)2 + (N-2)2 +....+1
2n2, where n is the main quantum number (the number of the shell).2n2, where n is the main quantum number (the number of the shell).2n2, where n is the main quantum number (the number of the shell).2n2, where n is the main quantum number (the number of the shell).
Your question reveals a common confusion between orbitals and shells. Chlorine has three electron shells: the first, second and third. The first shell has just the one orbital, the 1s The second shell has two sub-shells, the 2s and the 2p. There are three p orbitals in the 2p sub-shell. Each orbital can hold two electrons, so there are eight electrons maximum in the second shell. The third shell likewise has two sub-shells, the 3s and the 3p, but the 3p is not completely filled, leaving room for one more electron. When chlorine gains this electron it will become a Cl- ion. This is summed up in the electron configuration 1s22s22p63s23p5.
