Tritium, an isotope of hydrogen, or Helium-3 (which does not have a specific name).
Tritium, an isotope of Hydrogen
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
The mass of one mile of a compound is found by adding up the atomic masses of each of the component elements. A mole of Al2O3 has mass of 2 × 26.98 + 3 × 16.00 = 101.96g
Cobalt is an atomic mass of 58.93 atomic mass units
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
Its the atomic mass of carbon + the atomic mass of 3 oxygen. CO3 = C + 3(O) = 12.0107 + 3(15.9994) = 60.01
Tritium, or Hydrogen 3, has an atomic mass of 3.016.
No element in period 3 has an atomic mass of 12.
The atomic number of lithium is 3. The only stable isotope of lithium has 4 neutrons. Therefore its relative atomic mass is 7.
Lithium is an element with an atomic number of 3 and an atomic mass of 7.
Naturally occurring lithium contains two isotopes. The common one has an atomic mass of 7. About one per cent of the lithium has an atomic mass of 6.The atomic mass of Lithium-Li is 6.941 grams.
Deuterium, which is an isotope of hydrogen, has an atomic mass of 3. It has one proton and two neutrons in its nucleus.
Hydrogen is a non meta element. Atomic mass of it is 2.
The atomic weight of uranium is 238,02891(3) atomic mass units.
The atomic number is 3.
As Deuterium and Tritium are both merely isotopes of Hydrogen and not elements in their own right, they both have an atomic number of 1, just like Hydrogen (Hydrogen-1). Deuterium (Hydrogen-2) has an atomic mass of 2, and Tritium (Hydrogen-3) has an atomic mass of 3.
The atomic mass of the most common form of hydrogen is 1. There are isotopes of hydrogen with a mass of 2 (deuterium) and 3 (tritium), but they are rare.
