Want this question answered?
Number of electrons are lost by an atom in a chemichl reaction
valence electrons
Gaining electrons lead to decrease in oxidation state.
yes.they have the maximum number of electrons in their outer energy level?
The charge an element would have if it lost or gained electrons
there are five valence electrons in an atom of phosphorus
Chlorine gain electrons.
+1
80
it gains 4
In a redox reaction the number of electrons lost by one particle is equal to the number of electrons gained by another particle.
that depends on the number of electrons the more electrons the more energy
Aluminium will lose 3 electrons to form Al3+ ions.
Often there are the same number of electrons as there are protons. Exceptions to this are called ions, which have gained or lost an electron (can't be a proton lost or gained, that would change the element).
The oxidation number of an ionic atom or molecule is the number electrons that it has lost or gained.

It is called Oxidation number.
