You look at the atomic mass.. The number of neutrons is different for different individual atoms of the same element, each atom is also known an isotope. Looking at a periodic table, the atomic mass listed is the average atomic mass for all isotopes of that element found in nature.
Answer:
Balanced equations and mole ratios
In general, mole ratios can be used to convert between amounts of any two substances involved in a chemical reaction.

Explanation:
You see, all these materials we see around us are composed of elements. These elements are unique in their own ways!
Some of them are able to attract tiny negative particles called electrons close to their positive interior called the nucleus. This positive interior is so designated because it contains a positive particle called protons which attract these electrons.
Now, elements are broadly divided into metals and non metals. Protons in metallic elements are less able to pull electrons than protons in non metallic elements. As a result of this, non metals are mostly electronegative because they pull electrons towards themselves while metals are mostly electropositive because they give away their electrons easily. Fork is composed of metallic elements.
Since metals give away electrons easily, they can conduct electricity since electrons are the same charge carriers in electric circuits.
Also, in elements, there is a conduction band and a valence band. Electrons occupy the valence band but also move into the conduction band. The gap between the valence band and the conduction band in nonmetals is large hence they do not conduct electricity. The gap between the valence band and the conduction band in metals is minimal hence metals conduct electricity.
So if you stick that fork into a toaster, electrons can flow right through the toaster circuit into your body and cause you to be electrocuted.
