∙ 14y agoThe atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
Cobalt is an atomic mass of 58.93 atomic mass units
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.
Atomic number 6, atomic mass 12.

1 lanthanum atom has more mass than 100 hydrogen atoms and 4 sulfur atoms combined. Lanthanum has a higher atomic mass than hydrogen and sulfur, so even though there are more atoms in the other two compounds, the single lanthanum atom is more massive.
Lanthanum's atomic number is 57 thus it has 57 protons, the number of protons an atom has is equal to the atomic weight, in this case 141 minus the number of protons or 57 so, 141-57=84 Lanthanum-141 has 84 neutrons.
Lanthanum, with the chemical symbol La, is the chemical element with the atomic number 57.
Lanthanum has 57 protons and 81-82 neutrons.

Technetium (atomic number 43) is the inner transition metal with the lowest atomic number.
It is a metal with the symbol La its atomic number is 57. Its color is silver white.

Yes, lanthanum can conduct heat and electricity. It is considered a good conductor of electricity due to its metallic properties. In terms of heat conduction, lanthanum's atomic structure allows for the transfer of thermal energy through the material.
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
