how many valence electrons in potassium?
33459
K is the symbol for potassium, and the number of valence electron can be found through its' group on the periodic table. Hence, it has one valence electron.

The number of valence electrons is 5 + 3×7 = 26. If you draw a trial structure in which P is the central atom and every atom has an octet, you will have used 26 electrons. This is the correct number of electrons, so the trial structure is the correct structure.

What is the correct Lewis structure for potassium in KCl? - Yahoo. Best Answer: K is potassium. It has 1 valence electron Cl is chlorine, it has 7 valence electrons Since an atom needs 8 valence electrons to become stable.

Obviously, removing that electron gives us [Ar] (same configuration as K1+), which is a noble gas and has 8 electrons. Valence electrons are generally regarded as being 'the outermost electrons' for a given atom. Therefore, with neutral potassium, there is one valence electron.

A: An atom of a group 17 element such as chlorine has seven valence electrons. It is “eager” to gain an extra electron to fill its outer energy level and gain stability. Group 16 elements with six valence electrons are almost as reactive for the same reason.

This tells you that potassium has 19 protons and - since the number of protons is the same as the number of electrons- also 19 electrons. To find out the number of neutrons you have to look at the atomic mass or weight of the element.

Students should realize that each atom in a group has the same number of electrons in its outermost energy level. For instance, hydrogen, lithium, sodium, and potassium all have 1 electron on their outer energy level. Let students know that these electrons in the outermost energy level are called valence electrons.

Rubidium has one valence electron, which is located in the s-orbital of the atom's fifth energy level. Rubidium has a total of 37 electrons, illustrated in the element's electron configuration of 1s2 2s2p6 3s2p6d10 4s2p6 5s1. As there is only 1 electron in Rubidium's valence shell, Rubidium's valency is 1.

The electronic configuration of chlorine can be written as 2, 8, 7. 2, 8, 7 electrons are distributed in the shells K, L, M respectively. Therefore, valence electron in chlorine is 7 and it needs to gain 1 electron from the outermost orbit to attain octet. Hence, the valency of chlorine is 1.
