Answer:
Germanium
Explanation:
The element Germanium is one with a relative molecular mass of 72. This corresponds to the mass number of this element.
Relative molecular mass of an element is the mass of a formula unit to that of a carbon-12 atom.
The chemical symbol of Germanium is Ge. It is a lustrous and hard metalloid belonging to the carbon group.
It was discovered by Clemens Alexander Winkler.
A stock solution is a solution of a known concentration. Stock solution has a high concentration and therefore, the known amount of stock solution is used for preparing different concentrations, by diluting the same with the known amount of the solvent being used, such as water.
The atoms of some chemical elements have different forms, called isotopes. These break down over time in a process scientists call radioactive decay. Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter. Each isotope is identified with what is called a ‘mass number’. When ‘parent’ uranium-238 decays, for example, it produces subatomic particles, energy and ‘daughter’ lead-206.
