Answer:
the<u> atomic mass</u> of an element is the average mass of an element naturally occurring atom, or isotopes, taking into account the <u>percentage</u> of each isotopes
Explanation:
The atomic mass of an element is obtained by obtaining the relative abundances (in percentages) of naturally occurring atoms and the masses of the isotopes. The atomic mass can also be defined as the sum of the protons and the neutrons in the nucleus of an element.
In the periodic table, the atomic mass is indicated below the symbol of each of the elements and is usually in the decimal form.
Explanation:
A mixture is made of two or more substances that are not chemically combined whereas a compound is made of 2 or more elements that are chemically combined. The elements that make up the compound are combined in fixed ratios.
