Are the elements listed in order of atomic number or atomic mass?
The elements on the periodic table are listed in order of atomic number, which corresponds to the number of protons in the nucleus of each atom. The atomic mass of each element is typically listed below the element symbol and represents the average mass of the isotopes of that element.
What is its assigned atomic masss?
The atomic mass of an element is the average mass of its isotopes, taking into account their abundance in nature. It is typically listed on the periodic table below the element's symbol.
What does the atoimc mass of an element represent?
The atomic mass of an element represents the average mass of an atom of that element, taking into account the abundance of different isotopes of the element. It is measured in atomic mass units (amu) and is listed on the periodic table below the element's symbol.

Are Substances that are considered acidic are also called alkaline?
No, substances that are considered acidic are not called alkaline. Acids and alkaline substances are two different categories based on their pH levels. Acids have a pH below 7, while alkaline substances (also known as bases) have a pH above 7.
Alkaline solutions have pH values below 7?
Alkaline solutions have a pH higher than 7
Is 5.5 pH level acid or alkaline?
