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.

Why is hydrogen gas an element?
Hydrogen gas is an element because it is composed only of hydrogen atoms.
How is a molecule of hydrogen form from two hydrogen atoms?
Well with any element when two atoms are put together they are known as a molecule of that element. So one atom of hydrogen is known as one atom of hydrogen and two atoms of hydrogen is known as one molecule of hydrogen.
How many numbers of atoms does hydrogen have?
Hydrogen is an element, and the smallest form of an element is an atom. If you meant electrons, then 1.
How many atoms of each element can be found in a unit HC2H3O2?
2 Carbon atoms, 4 Hydrogen atoms, 2 Oxygen atoms
What is the letter to stand for hydrogen?
Hydrogen is an element - the simplest element at that. The chemical symbol for hydrogen is 'H' However hydrogen in its pure state is nearly always two atoms forming a molecule and is written H2.
