Question

Hydrogen , nitrogen , oxygen and sodium are compounds. T/F​

Answer 1

Answer:

         It is all TRUE. Hydrogen, Nitrogen, Oxygen, and Sodium are considered as Chemical Compounds.

Explenation:

         Hydrogen is the only element that forms compounds in which the valence electrons are in the n = 1 shell. As a result, hydrogen can have three oxidation states, corresponding to the H+ ion, a neutral H atom, and the H- ion. Nitrogen is an element that can combine with itself or with other elements to make different compounds. For instance nitrogen gas, N2, is a compound made when two nitrogen atoms form a chemical bond. It makes up about 80% of the atmosphere, while oxygen gas, O2, makes up a little less than 20% of the atmosphere. Oxygen in the atmosphere is a molecule because it contains molecular bonds. It is not a compound because it is made from atoms of only one element - oxygen. This type of molecule is called a diatomic molecule, a molecule made from two atoms of the same type. Sodium is highly reactive, forming a wide variety of compounds with nearly all inorganic and organic anions (negatively charged ions). ... The principal commercial sodium compounds are the chloride, carbonate, and sulfate. The most important and familiar sodium compound is sodium chloride, or common salt, NaCl.
