The element is sodium. Sodium atoms have a low electron affinity and will replace hydrogen atoms when placed into water. The reaction of sodium and water produces hydrogen gas that is ignited by the heat of the reaction. It should be noted that almost any element in the alkali and alkaline-earth groups will replaced hydrogen in water.
Compound
Hydrogen gas is an element because it consists of hydrogen atoms, which all have the same number of protons in their nucleus. This defines it as a pure substance made up of only one type of atom, which is a characteristic of elements.
In 3H3PO4, there are 3 hydrogen atoms, 3 phosphorus atoms, 12 oxygen atoms, and 4 additional hydrogen atoms for a total of 19 atoms.
Peroxide is not an element but it is an ion
D2O is a type of water known as heavy water, they use in candu reactors increasing its efficency. im not sure of what the elment "d" is but i do know that oxygene is the o so its basically the same as water h2o only that the mysterious elemnt d replaces the hydrogene
Deuterium oxide, also known as heavy water, is a soft white material that replaces hydrogen atoms in water. It has a higher density than regular water due to the presence of deuterium instead of protium.
All atoms in the beginning were hydrogen atoms.
Molecular hydrogen has two atoms, both which are of the same element - hydrogen.
hydrogen
C8H12 8 Carbon atoms + 12 Hydrogen atoms = 20 atoms total
Hydrogen is known as a element and a compound. Hydrogen is a light element with one proton and a gas compound with two hydrogen atoms.
Yes, hydrogen gas is a compound. It is made up of molecules which consist of two atoms of hydrogen, an element. It just happens that the same name is used for the gas as for the element.
C6H12O6. Six carbon atoms, 12 hydrogen atoms and six oxygen atoms.
Ammonia (NH3) has 3 hydrogen atoms. N is nitrogen.
hydrogen has only one proton and one electron. it is the lightest element and is a pure element, which means hydrogen is made of one type of atom (in this case hydrogen atoms)
hydrogen is an element because it cant be broken into its atoms easily..
Hydrogen.
