According to this rule we put electrons in the shells....here "n" show us the number of shell.
To balance the chemical equation N2 + O2 = N2O5, start by counting the atoms of each element on both sides. You would need to put a coefficient of 2 in front of N2 to balance the nitrogen atoms. Then, add a coefficient of 5 in front of O2 to balance the oxygen atoms. The balanced equation is 2N2 + 5O2 = 2N2O5.
Maximum of 2n2, where n is the energy level.
The number of electrons that can occupy each shell in an atom is determined by the formula 2n2, where n is the shell number.
The maximum is 18. This follows the law maximum = 2n2 where n = shell number, ie in this case n=3, 2n2=18.
The maximum number of electrons that can be present in each shell or subshell is determined by the formula 2n2, where n is the principal quantum number of the shell or subshell.
2n2 + 15n + 7 = 2n2 + n + 14n + 7 = (2n2 + n) + (14n + 7) = n(2n + 1) + 7(2n + 1) = (2n + 1)(n + 7)
2NH4NO3->2N2+O2+4H2O
n * 2n = 2n2
2 eyes on the road and 2 hands on the wheel
2n2 / n = 2n
yes
(n - 4)(2n + 3)
M5h 2n2
The balance is 2N2 +2O2= 4NO
Yes I can.
(2n - 3)(n - 6)
tn = 2n2 + 3n - 2
