This means that every atom of potassium has 19 protons in its nucleus. In a neutral atom, the number of protons is equal to the number of electrons. So the electron configuration of potassium will involve 19 electrons. The full electron configuration of potassium is 1s22s22p63s23p64s1 .

Valence electrons are the number of electrons present in the outermost shell of an atom. Now, the last shell of chlorine atom has 7 electrons in it. Therefore, there are 7 valence electrons present in an chlorine atom. Here, stable means that atom has not formed a ion yet.

The other inert gases including argon and xenon also have full outer shells with eight electrons. The inert gases have a valence number of 0.

Number of electrons in a chloride ion is 17. Hence, it needs one more electron to complete its octet. Its valence electrons are the number of electrons present in its outermost shell, i.e., 7.

The lowest energy level (the K shell) can only be occupied by two electrons, the L shell by 8 and the M shell by 18. The K shell electrons are closest to the nucleus. ... Electrons can't have whatever energy values they want, and each value is associated with a specific orbit trajectory.

The 3s23p5 electrons are the outermost electrons, so chlorine has seven valence electrons. In a picture, the valence electrons are the ones in the outermost shell.
8743
When the two atoms are in contact, potassium readily transfers its outer electron to chlorine which readily accepts it, resulting in both atoms achieving a state of eight outermost electrons. With this electron transfer, the ionic bond in KCl is formed.
