There are two oxidation numbers. P shows +5 oxidation number.
Because they will lose electrons and hence have positive oxidation numbers.
Assuming you mean what is the oxidation number of each atom in the compound C3H8O? Oxidation rules state the the sum of all oxidation numbers in a neutral molecule equals 0. 1. O = -2 2. H = +1 3. C = -2 These numbers are derived from... (-2) + (+1 x 8) + (-2 x 3) = 0
Barium in group 2 has just two oxidation numbers, 0 in the metal, +2 in its compounds.
+2 and +3 in its compounds.
There are two oxidation numbers. P shows +5 oxidation number.
All alkali earth metals have two valence electrons and they all form ions in +II oxidation state.
Because they will lose electrons and hence have positive oxidation numbers.
There are two oxidation numbers for magnesium. those are 0 and +2.
They both are metals with two oxidation states or levels (2 ox. numbers) but this isn't uncommon in group 14 (in the periodic table) e.g. C and Si also have 2 ox. numbers +2 and +4
Barium in group 2 has just two oxidation numbers, 0 in the metal, +2 in its compounds.

Oxidation -- (Iron Rust) ferric hydroxide and ferric oxide formed by oxidation. Hydrated Ferric Oxide causing deterioration at low tempuratures to metals containing Iron. Any film or coating on metals due to oxidation. Two pieces of metal containing Iron can be fused together by Rust.
Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only
Many metals have a possible +2 oxidation state. Some metals do obtain it preferentially, however: Group 12 metals (Zinc, Cadmium, Mercury) tend to have +2 oxidation states due to their electron configuration (d10, s2) retaining a full d orbital when 2 electrons are removed. Group 8 metals (like Iron) also commonly have +2 oxidation states, possibly due to the 'half filled shell' effect.
They are a series of elements, or metals, on the Periodic Table of Elements. The alkaline earth metals are: beryllium, magnesium, calcium, strontium, barium, and radium (i.e, the ones with two electrons in their outer shell and common oxidation state +2, right next to the alkali metals with common oxidation state +1). They're all silvery-colored and soft, and they combine with water to form alkaline hydroxides, but not as readily as the alkali metals do.
