Is helium a product of uranium decay?
Very little helium is present in Earth’s atmosphere. It is such a light element that Earth’s gravity cannot hold it. Helium is produced by the decay of uranium and thorium in granitoid basement rocks.
What is oxidation number charge for helium?
0
A helium atom has no charge, which means it has an oxidation number of 0.

The oxidation number of hydrogen in H-containing compound is +1.
What are the possible oxidation states of helium?
Electron configuration of Helium is 1s2. Possible oxidation states are 0. The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties.
What kind of oxidation state does uranium have?
Uranium is pyrophoric when finely divided. It is a little softer than steel and is attacked by cold water in a finely divided state.In air, uranium metal becomes coated with a layer of oxide. Acids dissolve the metal, forming the +3 oxidation state which oxidizes rapidly by water and air to form higher oxidation states.
What is the electron configuration of the element helium?
Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. The chemical symbol for Helium is He. Electron configuration of Helium is 1s2. Possible oxidation states are 0.
