Valence electrons are present in outermost shell. They are at far distance from nucleus.
This electron is a valance electron.
Valance electron
metallic bond
A valance electron is one that is associated with an atom. The valence orbit is the one that electron travels in.
That is a chemical change.
An atom is a nucleolus and an associated electron cloud. They bond by swapping OR sharing (valance or outer) electrons.
A core electron is an electron in an atom that is not easily removed or involved in chemical reactions. Core electrons occupy the inner energy levels of an atom and are tightly bound to the nucleus. They play a crucial role in determining the atom's chemical properties.
In an Atom!
A halogen is located in group 17 of the periodic table, so the electron configuration for the valance electron would be ns2np5 (n=energy level). So all halogens have 7 valance electrons.
The electron cloud in an atom is located outside of the nucleus.
No, they are located in the shells or orbits of an atom.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
