In the element 2C2H6 there are 4 atoms of Carbon (C) and 12 atoms of Hydrogen (H). To arrive at this answer multiply the superscript, the 2 in front of the equation. by the 2 after Carbon which equals 4. Next, multiply the superscript by the 6 behind Hydrogen which equals 12.
12
There are five atoms

Hydrogen is a non metal element. Atomic Mass of it is 1.
The name of the compound dinitrogen tetrahydride implies that the formula of the compound is N2H4. Therefore, each molecule contains two nitrogen atoms and four hydrogen atoms.
All atoms of the same element contain the same number of protons and electrons, but atoms of a given element may have different numbers of neutrons. Atoms with the same number of protons but different numbers of neutrons are called isotopes. An element has many isotopes--each with a close, but different number of neutrons.
