0 in elemental form and 2+ in its compounds.
In its elemental state, strontium has an oxidation state of zero. When it forms salts its normal oxidation state is +2.
+2 for Strontium and -1 for each hydrogen in SrH2.
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
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
Oxidation number of Se is +6. Oxidation number of O is -2.
Charge
Strontium is located in group 2 of the periodic table. Hence it has two valence electrons. The oxidation number atomic strontium is 0 where that of strontium ion is +2.

1+ is the normal oxidation number for hydrogen
The oxidation number in sodium hydride are:Na +1 andH (in hydrides like this) it is -1
2
Its oxidation number is -1, which is uncommon for hydrogen.
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.
When it has gained one electron, forming Hydride ions
Hydrogen has an oxidation number of 0 in H2. In compounds it is generally +1, the exception is when it is present as the hydride ion, H- , when has an oxidation state 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
The oxidation number of hydrogen in KH is -1, because the only oxidation number for potassium in a simple inorganic compound is +1. A hydrogen atom can complete its outer electron shell by adding one electron acquire the electron configuration of helium, and this is what happens during the formation of alkali metal hydrides such as KH.
