Review of Short Phrases and Links

    This Review contains major "Atomic Mass Units"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. Atomic mass units are very small. (Web site)
  2. Its value in atomic mass units (u) is approximately equal to the sum of the number of protons and neutrons in the nucleus of the atom.

Four Atomic Mass Units

  1. Alpha particles have two positive charges and a mass of four atomic mass units; they are identical to helium nuclei. (Web site)

Chemical Formula

  1. It has a chemical formula of C4H5N3O and a molecular weight of 111.10 atomic mass units. (Web site)

Atomic Weights

  1. Problem 2: Listed in the following chart are the atomic weights (measured in atomic mass units) for natural silver and its two isotopes.

Average Atomic Mass

  1. For example, a sample of chlorine contains 75.8% chlorine-35 and 24.2% chlorine-37, giving an average atomic mass of 35.5 atomic mass units. (Web site)

Nucleus

  1. The difference between the actual mass of the nucleus measured in atomic mass units and the number of nucleons is called mass excess i.e. (Web site)

Different Elements

  1. Furthermore, the weights of different elements will not accord exactly with the number of atomic mass units they possess. (Web site)

Chemists

  1. Hence, before 1961 physicists as well as chemists used the symbol amu for their respective (and slightly different) atomic mass units.

Element

  1. Listings of atomic weights or unified atomic mass units usually average the isotopes of an element. (Web site)

Particular Element

  1. The mean atomic mass of a particular element in atomic mass units. (Web site)

Atoms

  1. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. (Web site)

Atom

  1. The average mass of an atom of an element, usually expressed in atomic mass units. (Web site)

Masses

  1. Physicists, and some chemists, measure the masses of individual atoms in kg, g, or atomic mass units. (Web site)
  2. It is possible to measure the masses more precisely in atomic mass units, but not to convert them more precisely into kilograms.

Small Masses

  1. Prof. Harman also introduces atomic mass units, or amu's, which are a more convenient unit for describing the very small masses of atoms. (Web site)

Mass

  1. Answer: The binding energy is the difference in mass between helium (4.003) and hydrogen (4x1.008), in atomic mass units.
  2. As its name suggests, the average atomic mass provides the average value of mass—in atomic mass units (amu)—for a large sample of atoms. (Web site)
  3. A figure used by chemists to specify the mass — in atomic mass units — of the average atom in a large sample. (Web site)

Mass Defect

  1. The mass defect is so small that using atomic mass units will result in a completely wrong answer. (Web site)

Atomic Mass

  1. The atomic mass (ma) is the mass of an atom at rest, most often expressed in unified atomic mass units. (Web site)
  2. The atomic mass of an atom decreases by four atomic mass units when it emits an alpha particle.

Atomic Mass Units

  1. The atomic mass–u (or atomic weight) is the mass of an atom in atomic mass units.
  2. Let M represent the numerical value of the mass of one atom of any chemical element in atomic mass units. (Web site)
  3. Atomic weight is the weight of an atom expressed in atomic mass units (amu). (Web site)
