You are watching: How many valence electrons are in potassium


All valence electron(s) that potassium ion have a various orbital angular momentum quantum number 보다 valence electron(s) the potassium


Valence electron(s) that potassium has a higher principal quantum number 보다 valence electron(s) that potassium ion


Correct answer:

Valence electron(s) the potassium has a higher principal quantum number than valence electron(s) that potassium ion


Explanation:

Potassium has one valence electron. This way that there is one electron in the outermost covering (4th shell). Potassium ion, ~ above the other hand, loser an electron and has a finish octet (has eight valence electrons) in its third shell. Recall the the principal quantum number signifies the shell. Due to the fact that the valence electron that potassium is uncovered in the 4th shell,

*
. Similarly, the valence electrons of potassium ion are uncovered in the third shell and
*
 for them. Valence electron the potassium has actually the greater principal quantum number.

Orbital angular momentum number (

*
) is the second quantum number and also it signifies the kind of orbital. The is constantly greater 보다 or equal to zero. Over there are 4 main types of orbital: s, p, d, and f. Each orbital deserve to hold 2 electrons. In a provided shell, there room one ‘s’ orbital, 3 ‘p’ orbitals, 5 ‘d’ orbitals, and seven ‘f’ orbitals. ‘l’ = 0 because that ‘s’ orbitals, ‘l’ = 1 because that ‘p’ orbitals, ‘l’ = 2 for ‘d’ orbitals, and also ‘l’ = 3 for ‘f’ orbitals. In potassium, over there is only one valence electron; therefore, there is just one electron in the 4th shell and it deserve to fit into the ‘s’ orbital. In potassium ion, there space eight valence electrons; therefore, two electrons deserve to be uncovered in the ‘s’ orbital and also the staying six electrons deserve to be uncovered in the 3 ‘p’ orbitals. Not all valence electrons of potassium ion and also potassium have various ‘l’ value. This is since valence electron that potassium and also two the the valence electrons of potassium ion are uncovered in the ‘s’ orbital (

Electrons uncovered in higher shell number have greater energy. Valence electron the potassium is uncovered in the fourth shell; therefore, the will have actually a higher energy than any kind of of the valence electrons of potassium ion.
