The first 20 elements in a periodic table are Hydrogen ( H - 1), Helium ( He - 2), Lithium ( Li - 3), Berelium ( Be - 4), Boron ( B - 5), Carbon ( C - 6), Nitrogen ( N - 7), Oxygen ( O - 8), Fluorine ( F - 9), Neon ( Ne - 10), Sodium ( Na - 11), Magnesium ( Mg - 12), Aluminium ( Al - 13), Silicon ( Si - 14), Phosphorus ( P - 15), Sulphur ( S - 1.
How to calculate valency of 1st 20 elements YouTube
The valence electrons for main group elements are those with the highest n level. For example, gallium (Ga, atomic number 31) has the electron configuration [Ar]4s 2 3d 10 4p 1, which contains three valence electrons (underlined - 4s 2, 4p 1). The completely filled d orbitals count as core, not valence, electrons. Transition elements or.

The oxidation state tells how many valence electrons an atom accepts (negative number) or donates (positive number) to form a chemical bond. A lithium atom has one outer shell electron. It has a valence of 1. Usually it's oxidation state is +1, but it can lose the electron and have a valence of -1. The most stable oxidation state is one that.
