Answer:
A measure of an element's identity is determined by its atomic number, and its weight is determined by its atomic mass.
Step-by-step explanation:
The amount of protons in the nucleus of an element's atom is known as the element's atomic number. It serves to identify and categorize the elements in the periodic table and is particular to each element. The chemical characteristics of an element are determined by its atomic number.
An element's atomic mass is its average atom's mass, which is typically expressed in atomic mass units (amu). It is the total number of protons and neutrons in the nucleus of an atom. The atomic mass can be a decimal and is not always a number.
