Atomic Mass Unit

Mass of an atom, taken on a scale where the mass of a carbon atom is 12u. In elements that consist of different isotopes the mid range mass of the isotope mix is given.

The mass of one particle

Isotopes are forms of a chemical element whose nuclei have the same atomic number, Z, but different atomic masses, A. The word isotope, meaning at the same place, comes from the fact that all isotopes of an element are located at the same place on the periodic table.

This box can be used to specify the units of the initial amount of the substance. e. g. grams, pounds, etc.

The small, positively charged center of an Atom, in which Protons and Neutrons are found.

Hong Kong led, with over 318,000 units seized in 1995, followed by the United States, with around 300,000, Egypt with 178,000, Japan 80,000 and Indonesia 48,000.

We also all know that atoms are not the end of the story.

And that's because we're measuring the weight so precisely that carbon comes in different isotopes, so if it has an extra neutron on it, we actually measure it as a different chemical.

Isobars are nuclides having the same mass number, i. e. sum of protons plus neutrons.

Reported seizures rose from 217,000 units in 1990 to over 1.3 million in 1993 and 668,000 in 1994, reaching a new record total of more than 3 million units in 1995.

Quantity units and quantity estimations

In contrast, the up and down quarks have very large masses, and combine in threes to make the protons and neutrons inside atoms.

These particles must have just as much mass and energy as is carried in by the proton and anti proton.

Matter that cannot be broken down into simpler matter. Chemical elements are cornerstones of Materials. Elements consist of atoms that consist of a nucleus of positive protons, neutral neutrons, and a shell of electrons.
