Valence electrons are those in the outermost shell of the atom.
one
Potassium has 1 valance electron.
The Lewis structure for K3N would show three potassium (K) atoms each bonded to a nitrogen (N) atom. Potassium has one valence electron, while nitrogen has five valence electrons. The structure would display the bonding pairs between the potassium and nitrogen atoms.
In the compound Al₂O₃, there are two aluminum (Al) atoms and three oxygen (O) atoms. Aluminum has 3 valence electrons, so 2 Al atoms contribute a total of 6 valence electrons. Oxygen has 6 valence electrons, so 3 O atoms contribute 18 valence electrons. Therefore, the total number of valence electrons in Al₂O₃ is 6 + 18 = 24 valence electrons.
The valence electrons are involved in the chemical bonding of atoms in a molecule.
Calcium has more valence electrons than potassium. Potassium has only 1 valence electron, while calcium has 2 valence electrons.

the valency of potassium is 1
Potassium has 1 valance electron.
valence electrons
Oxygen atoms have 6 valence electrons, while sulfur atoms have 6 valence electrons as well.

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).
the electrons on their outer shell, all atoms want to gain a full valence shell.
