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).
The quantum shell or the principle shell (represented by an integer known as the principle quantum number, n) are orbits found in an atom. It is arranged as n=1, n=2, and so forth, n=1 being closest to the nucleus. As the numbers increase, so do the energy. Each quantum shell is an orbit, and in the orbits exist sub-orbitals. Please see sub-orbitals for more details.
