Well, honey, the oxidation number of strontium in the hydride of strontium is +2. It's like asking if Betty White is a national treasure - the answer is obviously yes. So, in this case, strontium is happily rocking that +2 oxidation number like a boss.
strontium (which the atomic number is not 85 its 38) has 38 protons and 50 neutrons... hope this helps!
1+ is the normal oxidation number for hydrogen
The atomic number for strontium chloride is determined by the element strontium, which has an atomic number of 38. Since chloride is an anion with a charge of -1, it does not affect the overall atomic number of the compound.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
Strontium-88 is an isotope of strontium that has 52 neutrons. It has an atomic number of 38, therefore the total number of neutrons (52) is obtained by subtracting the atomic number from the mass number.
In the compound hydrides such as lithium hydride (LiH) or sodium hydride (NaH), hydrogen has an oxidation number of -1.

Strontium has 2 valence electrons because it is in Group 2 of the periodic table. The oxidation number of strontium is typically +2, as it tends to lose those 2 valence electrons to achieve a stable electronic configuration.

Strontium is in the second group. It shows only +2 number.
Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium all have an oxidation state of plus 2.
The oxidation number of Na in NaH is +1 because alkali metals like Na typically have a +1 oxidation state in compounds. The oxidation number of H in NaH is -1 because hydrogen usually has a -1 oxidation state when bonded to metals.
The oxidation number of hydrogen in a compound other than a hydride is typically +1. This is because hydrogen usually forms covalent bonds where it shares an electron with another nonmetal, resulting in a slight positive charge on the hydrogen atom.
The oxidation number of oxygen in hydroxide (OH-) is -2 since oxygen typically has an oxidation number of -2 in compounds. The oxidation number of hydrogen in hydroxide is +1 since hydrogen usually has an oxidation number of +1 when bonded to nonmetals like oxygen.
In Sr(OH)2, strontium (Sr) has an oxidation number of +2 because it belongs to Group 2 of the periodic table. Oxygen (O) typically has an oxidation number of -2, so each hydroxide ion (OH-) has an oxidation number of -1.
Think about it, the overall charge of CaH2 is neutral (meaning a charge of 0). One of the oxidation rules states that H has a charge of -1 if it is apart of a hydride (Ex LiH, CaH2 is also a hydride). Because there are 2 Hs, it's charge would be -2. If you add the charge of calcium which is 2 with the hydrogens charge -2 you would get 0, which is right because the molecule is neutral. 1- Apex
