The mass of a single tellurium atom, in grams, equals 2.118 x 10⁻²² grams
Further explanation
Within the atom is a nucleus made up of three fundamental particles: protons, neutrons, and electrons that orbit around the nucleus.
Protons carry a positive charge (+1), electrons have a negative charge (-1), and neutrons are neutral (uncharged).
The mass of a proton is equal to that of a neutron, which is approximately equal to 1 amu, whereas an electron has a smaller mass.
Atomic mass reflects the average atomic mass of all isotopes.
The mass of an atom is determined relative to 1 carbon-12 atom, which has a mass of 12 amu.
The atomic mass unit (amu) represents 1/12 of the mass of a carbon-12 atom.
The 'amu' has now been replaced by the unit 'u'.
The hydrogen atom is recognized as the lightest atom, with a mass of 1.67 x 10⁻²⁷ kg as measured by a mass spectrometer, commonly simplified to 1 amu.
1 amu = 1.66 x 10⁻²⁴ grams
For instance, carbon-12 has an atomic mass of 12 amu and carbon-13 has an atomic mass of 13 amu.
Single atoms of tellurium have a mass of 127.60 amu.
Thus, the mass in grams can be calculated as:
mass = 127.60 amu x 1.66 x 10⁻²⁴
mass = 2.118 x 10⁻²² grams
