If you find an element that exists as only one isotope, then the atomic mass and the atomic weight will be the same. Atomic mass and atomic weight may equal each other whenever you are working with a single isotope of an element, too. In this case, you use the atomic mass in calculat...
Understand the definition of atomic mass, atomic number, and atomic weight. Discover how to find atomic mass, and learn what an atomic number...
Which particles in the atom of an element designate the atomic number? What is the mass number of an oxygen atom with 7 neutrons? What is the atomic mass/weight of an atom that has 24 protons, 26 neutrons, and 24 electrons? How many elements have an atomic number of 42?

The meaning of ATOMIC VOLUME is the quotient obtained by dividing the atomic weight of an element by its specific gravity.
Atomic Weight of Csium: Use of the Word 'Mass-spectrograph' THE first mass-speetra obtained from caesium by means of a hot anode showed only one line of mass number 133. As I pointed out,the conditions of the experiment precluded any accuracy of measurement sufficient to decide whether the...
Atomic mass unit (AMU) 1/12 the mass of a neutral atom of 12C, equal to 931.5 MeV. Atomic number (Z) Integer equal to the number of protons in a nucleus; the order of an element in the periodic table. Atomic weight or nuclear mass number (A) An integer equal to the sum of the...
Define atomic weight. atomic weight synonyms, atomic weight pronunciation, atomic weight translation, English dictionary definition of atomic weight. n. The average mass of an atom of an element, usually expressed relative to the mass of carbon 12, which
The atomic mass ofhydrogenis 1.0079. The atomic weight ofboronsamples collected on Earth falls within a range of 10.806 to 10.821. Synthetic Elements For synthetic elements, there is no natural isotope abundance. So, for these elements, the total nucleon count (sum of the number of protons and...
