when it is on the very outside level away from the nucleus
A valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.)
It is an electron in the outermost shell of the atom.
What else can I help you with?
An electron in the outermost energy level of an atom is a?
The outermost electrons are called VALENCE electrons.
What is the number of valence electrons for Li and K?
Both lithium and potassium have one valence electron
Hydrogen has how many valence electrons?
One. A hydrogen atom contains only one electron, and it is a valence electron.
How many valence electrons are in alkali metals?
one valence electrons
What is the number of valence electrons in Na?
Na has one valence electron i.e. 1 electron in valence(last) shell.
Are valence electrons located in the electron cloud?
The outermost shell of an electron is called the valence shell. This shell may or may not have electrons.The valence shell is a part of the electron cloud.So your answer isYes, the valence electrons are located in the electron cloud.
How many valence electrons does an atom of potassium have?
4
What is the number of valence electrons the element hydrogen has?
One.Hydrogen has only 1 electron in total, and it is also a valence electron.
Is a valence electron the same thing as a electron?
Yes, but valence electrons are always in the outer electron shell of an atom.
How many valance electrons does hydrogen have?
Hydrogen has only one electron. Just the one. And it is a valence electron.
How many valence electron does alkali metals have?
Alkali metals have one valence electron.
How many valence electrons does the element cesium have?
A cesium atom has 1 valence electron. It is an alkali metal, and all alkali metals have 1 valence electron. The electron configuration for cesium is (Rn)7s1. The single electron in the 7s sublevel is its valence electron.
