The mass number indicates the sum of the number of protons and neutrons of the isotope. The mass number, nucleon number or atomic mass indicated about the respective chemical symbols in the Periodic Table are average figures based on the different isotopes and their relative abundance. That is why there are decimals in mass numbers in the periodic table. It can be used to compare the relative atomic masses of different atoms.
The mass number of gold is 197. This number represents the total number of protons and neutrons in the nucleus of a gold atom.
The mass number of an atom of argon is 40. This number represents the total number of protons and neutrons in the nucleus of the argon atom.
The mass number for carbon is 12, which represents the total number of protons and neutrons in the nucleus of a carbon atom.
Potassium is a metal element. Atomic mass of it is 30.
Mass number!:)
The mass number is the sum of the neutrons and protons which exist in the atomic nucleus of an isotope.
The mass number
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.
The mass number is sum of neutrons and protons in the atomic nucleus.
This is the mass number.
The atomic number represents the number of protons. The atomic mass represents the number of protons + neutrons.
It represents the atomic number and atomic mass. Mass number is the superscript Atomic number is the subscript
You get the number of neutrons in the atom. The mass number represents the total number of protons and neutrons in the nucleus, while the atomic number represents the number of protons. Subtracting the atomic number from the mass number gives you the number of neutrons because the difference accounts for the protons.
mass number
The mass number represents the total number of protons and neutrons in an atom's nucleus. It determines the isotope of an element. The atomic number represents the number of protons in an atom's nucleus, defining the element and its unique properties on the periodic table.
The mass number of gold is 197. This number represents the total number of protons and neutrons in the nucleus of a gold atom.
The mass number of an atom of argon is 40. This number represents the total number of protons and neutrons in the nucleus of the argon atom.
