The atomic number refers to the number of protons in the element. And since the number of protons = number of electrons, the atomic number is also the number of electrons in the element.
The mass number of an element refers to the number of neutrons and protons in the element. &since electrons are negligible in mass, the number of neutrons can be found out by subtracting the atomic number from the mass number.
Take for example, oxygen. Oxygen has an atomic number of 8 and a mass number of 16.
Hence, from the atomic number it can be derived that it has:
8 electrons
8 protons
While from the mass number, it can be derive that it has:
16-8 = 8 neutrons

What is the atomic mass number of krypton?
83.98 amu is the Atomic Mass, 36 is the atomic number.
Is it true that The atomic mass is equal to the atomic number?
No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.
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 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
How much is the atomic mass and atomic number for corbon?
Carbon is a chemical element with an atomic number of 6 and an atomic mass of about 12.011 atomic mass units.
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.
How do you know the number of neutrons an atom has?
You can find the number of neutrons in an atom by subtracting the atomic number (number of protons) from the atomic mass number (rounded atomic weight). The atomic mass number represents the sum of protons and neutrons in the nucleus.
Difference between atomic and mass number?
Atomic number shows the number of protons in an element and the mass number shows the number of protons+neutrons In an electrically neutral atom, atomic number is also the number of electrons .
What elements have the atomic number 12 and atomic mass 8?
There is no element with an atomic number of 12 and an atomic mass of 8. Atomic number corresponds to the number of protons in an atom, while atomic mass is the sum of protons and neutrons. The atomic number of an element cannot be smaller than its atomic mass.
What is phosphorus' atomic number and atomic mass number?
Atomic number for p is 15. atomic mass for p is 31.
