What element has the atomic number 74?Numbered Mass:The atomic number of an element refers to the number of protons/electrons located in the nucleus of an atom of that element. The atomic mass is the sum of the number of protons and the number of neutrons....
Each element in theperiodic tableconsists of atoms, and each atom has a unique atomic mass and unique atomic number. The atomic number refers to the number of protons in the atom's nucleus, while atomic mass reflects the sum of the number of protons and neutrons. It is expressed in AMU ...
The atomic number refers to the number of protons in an atom of an element. It also uniquely identifies the element. When you look at the periodic table, you'll see the atomic number of each element listed in the upper left corner. If you find the element...

The total mass of the atoms is the sum of the masses and is given in atomic mass units (amu)a or the “Z” of the material. Isotopes of an element have different masses due to differing numbers of neutrons in the nucleus. For example, hydrogen can be 1H (1 proton) or 2H (...
In addition, the number of proton in the nucleus of an element makes up theatomic number.A proton mass is slightly little less than a neutron. Besides, one or more protons are present inside the nucleus of an atom and they are a necessary part of the nucleus of an atom. ...
