The number 174 in platinum refers to mass number or A. This is applicable to atomic nuclei of Pt 174 isotope.
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
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.
Platinum is a metal element. Atomic mass of it is 195.
The atomic mass of platinum (Pt) is approximately 195.08 atomic mass units.
Platinum has the atomic weight (not mass) 195,084.
Platinum is a meta element. Atomic mass of it is 196.
The atomic radius of platinum is about 139 picometers (pm).
Platinum is a rare element too. Atomic number of platinum is 78.
Platinum is a metal element. Atomic mass of it is 195.
Platinum is a meta element. Atomic mass of it is 195.
The atomic number of platinum is 78, which means it has 78 protons in its nucleus. The atomic mass of platinum is approximately 195.08 g/mol, which is an average of the different isotopes of platinum found in nature.
When measuring mass, you need a unit of measurement, not a dimensionless number. In the case of an atom, you would use atomic mass units. Platinum weighs a lot more than 3.25 atomic mass units. It is a heavy metal.
It represents the atomic number and atomic mass. Mass number is the superscript Atomic number is the subscript
The element with a mass of 190 is an isotope of platinum, specifically platinum-190. This isotope is not naturally stable and is radioactive.
