The valence electrons of which element has the highest energy hydrogen lithium sodium or potassium?

The element with the highest energy valence electrons among hydrogen, lithium, sodium, and potassium is potassium. Potassium is in the first group of the periodic table, which means it has one valence electron located in the highest energy level (n=4 in the case of potassium).


What is the number of the prinicpal energy level in which valence electrons are found?

The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present

Valence electron are found in what energy level?

Valence electrons are found in the outermost energy level of an atom, also known as the highest principal energy level. These are the electrons involved in chemical bonding and determining the reactivity of an element.
