Hydrogen, it only has one electron and therefore can bond with almost every element
(with the exception of the nobel gasses, they already have a full outer electron shell)
No, iron is an element. Chrmium is also an element, so there are no other substances, compounds or otherwise, that are found in it. However, there are alloys that contain both iron and chromium along with other metals.
Yes, gold is an element.Yes It is-see AU on table
Sodium
Cobalt is an element, and is a transition metal with atomic number 27.
Pure antimony is a pure element. No element can be broken down into a simpler substance by any means. Molecules and compounds that contain antimony, however, can easily be broken down into the pure element.
no, it is most commonly found as a compound
Sodium
hydrogen is most commonly found as a part of water with oxygen.

Although Hydrogen is the most abundant element in the universe, it is only found in trace amounts on Earth. However, one of it's compounds fills around 70% of the world's surface: Water: H2O: Hydrogen Oxide.
