because it is an isotope???
why is the atomic mass of technitium usually in brackets?
relative atomic mass
All elements have an atomic mass relative to 12C having a mass of 12.
Chlorine (Cl) Atomic Number: 17 Relative Atomic Mass: 35.453
Bexause its similar with the atomic mass
why is the atomic mass of technitium usually in brackets?
relative atomic mass
relative Atomic Mass
the relative atomic mass for the element potassium is 39.0983
It's an average number allowing for the relative abundances of different isotopes.
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.
All elements have an atomic mass relative to 12C having a mass of 12.
The relative atomic mass is 186.207
The Relative Atomic Mass of Sodium is 23.
The relative atomic mass is 180.948
Each element on the periodic table has two numbers: the atomic number and the relative atomic mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.
Chlorine (Cl) Atomic Number: 17 Relative Atomic Mass: 35.453
