Hydrogen

The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope. (Atomic mass is also referred to as atomic weight, but the term 'mass' is more accurate.)

Atomic Number For Hydrogen Ion

For instance, it can be determined experimentally that neon consists of three isotopes: neon-20 (with 10 protons and 10 neutrons in its nucleus) with a mass of 19.992 amu and an abundance of 90.48%, neon-21 (with 10 protons and 11 neutrons) with a mass of 20.994 amu and an abundance of 0.27%, and neon-22 (with 10 protons and 12 neutrons) with a mass of 21.991 amu and an abundance of 9.25%. The average atomic mass of neon is thus:

0.9048×19.992 amu=18.09 amu
0.0027×20.994 amu= 0.057 amu
0.0925×21.991 amu= 2.03 amu
20.18 amu

Atomic Number Of H

The atomic mass is useful in chemistry when it is paired with the mole concept: the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element. Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams. The same concept can be extended to ionic compounds and molecules. One formula unit of sodium chloride (NaCl) would weigh 58.44 amu (22.98977 amu for Na + 35.453 amu for Cl), so a mole of sodium chloride would weigh 58.44 grams. One molecule of water (H2O) would weigh 18.02 amu (2×1.00797 amu for H + 15.9994 amu for O), and a mole of water molecules would weigh 18.02 grams.

The original periodic table of the elements published by Dimitri Mendeleev in 1869 arranged the elements that were known at the time in order of increasing atomic weight, since this was prior to the discovery of the nucleus and the interior structure of the atom. The modern periodic table is arranged in order of increasing atomic number instead.

About Hydrogen

Known as the most abundant and the lightest chemical element in our Universe, hydrogen is a type of gas without color and smell, which also has the lowest density of all gases. It is believed to be the first atom produced in our Universe after the Big Bang, and all other elements were further produced from hydrogen as a result of nuclear fusion. The name of the gas is formed from two Greek words, meaning water and forming, so this is the element which creates water. Since hydrogen is a part of water molecule, it is an absolutely essential chemical element for life, which can be found in all living bodies on our planet. It is extensively used in a large variety of industrial branches, from chemical industry (producing fertilizers, etc) to electronic (substance producing) and food industry, etc. One more very important point is: hydrogen is now seen as a source of clean eco-friendly fuel of the future, which will help the humanity to solve the problem of pollution and being gas/oil dependent.

Uses of Hydrogen

Hydrogen is mostly used in the petroleum and chemical industries. The most important use of hydrogen in the world is in ammonia manufacture for the fertilizer market. The other significant use of this chemical element is in fossil fuel processing. Today, liquid hydrogen is used as a primary fuel of the American space program by The National Aeronautics and Space Administration (NASA). Hydrogen is also used in various industrial fields such as metalworking and as a coolant in generators in power stations.
