Atomic number is the number of protons in the nuclei of the atoms of a given element. The elements on the Periodic Table are arranged according to increasing atomic number. For example, carbon's atomic number is 6, so it has 6 protons in the nuclei of all of its atoms.
Mass number is the number of protons and neutrons in the nuclei of the atoms of a particular isotope of an element. For example, carbon-12 is an isotope of carbon that has 6 protons and 6 neutrons in the nuclei of its atoms. However, carbon-14 is an isotope of carbon that has 6 protons and 8 neutrons in the nuclei of its atoms.

∙ 15y agoAtomic Number: Number of protons in the atom. Defines which element it is.
Mass Number: The average mass of the atoms of a given element. The mass is the sum of the protons and neutrons. This is an average because the different isotopes exist in different quantities.
Isotopes: Atoms of the same element (equal number of protons) but with different number of neutrons.
Ex. Hydrogen has 1 proton. Over 99% of the hydrogen if composed of a single proton but there are two other isotopes for hydrogen: deuterium (1 proton and 1 neutron) and tritium (1 proton and 2 neutrons). If you check the periodic table, the Atomic Mass of hydrogen will be 1.00794 because a small percentage of the hydrogen has atomic mass larger than 1.

What is the atom with same atomic number but different mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the atomic number and mass of boron?
Atomic Number = 5 Atomic Mass = 10.811
How can you determine the number of neutrons in an atom if its mass number and its atomic number are known?
It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.
What is Sulfur's mass number and atomic number?
Sulfur has atomic number 16 and atomic mass 32.
What is the atomic number and the mass number of an element with 20 atomic number and 23 mass number?
Sodium is a metal element. Atomic mass number of it is 23.
What is the difference between the atomic number mass number and atomic mass?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the difference between mass number atomic mass and atomic number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the atomic mass number of krypton?
83.98 amu is the Atomic Mass, 36 is the atomic number.
What do you do with an atomic number and an atomic mass?
The atomic number is the number of a chemical element in the periodic table of Mendeleev; the atomic number is equal to the number of protons and electrons. The atomic mass is the mass of an atom expressed in relative atomic mass units.
Can you use the atomic number and atomic mass to calculate the number of each subatomic particle?
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
What is atomic mass and atomic number for radium?
The atomic number is 88 and the atomic mass is 226
Is it true that The atomic mass is equal to the atomic number?
No, the atomic mass number is the number of protons plus the number of neutrons. The atomic mass of an atom is the total mass in a motionless atom.
In order to calculate the number of neutrons you must subtract the from the?
Number of neutrons = Mass number - atomic number
What is the difference between the atomic number and the atomic mass?
Atomic mass is the mass of 1 mole of the element. Atomic number is the number of protons the element has
What is the relationship btw atomic mass and atomic mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the atom with same atomic number but different mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What does atomic mass do?
The atomic mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
