The 4th energy level of an atom is also known as the N shell. Potassium, which has 20 electrons as 2,8,8,2 shell configuration, has 2 electrons in N shell.
we know that 1st shell contain 2 electrons 2nd shell 8 electrons but third shell have to contains 18 electrons but the maximum no. of electrons that can be accommodated in the outermost orbit is 8 electrons...... by yhell
Potassium has one electron on its outer shell. It belongs to group 1 of the periodic table, so it has one electron in its outermost shell.
The penultimate shell can accommodate a maximum of 8 electrons. This is based on the maximum number of electrons that can occupy each subshell within the penultimate shell (s = 2 electrons, p = 6 electrons).
no electron is present in the outer most shell of hydrogen ion
In Argon, Potassium and Calcium, the limit is eight, but because of the overlapping energy levels, In everything from Scandium upwards, the limit is eighteen.
Two electrons can fit in the first shell

There are 19 electrons in the potassium nucleus.

A potassium atom typically has 19 protons and 19 electrons. The number of protons defines the element, so potassium always has 19 protons. In a neutral atom, the number of protons and electrons is the same.
Potassium (K) typically has 1 valence electron. It readily loses the lone outer electron leaving a strong shell of 8.
In Argon, Potassium and Calcium, the limit is eight, but because of the overlapping energy levels, In everything from Scandium upwards, the limit is eighteen.
Potassium needs to lose 1 electron to achieve a full outer shell, as it has 1 electron in its outermost shell. By losing this electron, potassium can achieve the stable electron configuration of the nearest noble gas, argon.
1 in the 4s orbital, 19 electrons in all (K has an atomic number of 19)
Potassium is in group 1 of the periodic table, so the answer is 1 electron.
