The mass number is the total number of protons and neutrons in an atom's nucleus, while the atomic number is the number of protons in the nucleus. The mass number determines the atom's mass, while the atomic number determines the element's identity on the Periodic Table.

The number of neutrons in an atom can be found by subtracting the atomic number from the?
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
Any particular element can always be identified by its?
Atomic Mass
How can you use the word atomic radius in a sentence?
Please tell me your atomicnumber.You just did 'use atomic number in a sentence' by putting this question on-screen.You could even read the above question and answers aloud, and you will have done it again.I just couldn't believe my eyes when I realized that an atomic number is revealed by the number of protons in the nucleus of an atom!"What is your atomic number?" is NOT a good pick-up line, unless you are speaking to a scientifically-minded person.The atomic number of Helium is 2."The atomic number of Sulfur is 16."(Note that atomic number means the number of protons in the atom, that's why the term proton number is interchangeable with atomic number.)See the related Wikipedia link listed below for more information:
How many nuetrons are in the element oxygen?
The element oxygen has 8 neutrons. It has an atomic number of 8 and an atomic mass of around 16, with the atomic mass being the sum of the protons and neutrons in the nucleus.
What is the approximate mass of a neutral atom with 31 electrons and 38 neutrons?
The mass of an atom is primarily determined by the protons and neutrons it contains since electrons have negligible mass. With 38 neutrons and an atomic number of 31 (which corresponds to the number of protons), this atom is likely a neutral atom of gallium. The approximate mass of this neutral atom can be calculated using the atomic mass of gallium (around 69.7 g/mol).
What best describes the number of neutrons in an atom?
It is equal to the difference between atomic number and Atomic Mass number. A+
What is the difference between the atomic number an its atomic mass?
Atomic number is the amount of electrons. Atomic mass is the amount of protons and 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 is the difference between the atomic number and average 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 atomic number and atomic mass weight?
Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
What is the difference between atomic mass and atomic weight?
Atomic Mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
What is difference between atomic weight and atomic mass?
Atomic Mass is the mass of an atom in Atomic Mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
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 is the difference between atomic mass unit and atomic mass?
Atomic mass unit is the number on the bottom of the Chemical. However, the atomic mass is the number on the top of the chemical minus the number on the bottom. b.t.w The no. of neutrons = top no. minus bottom no.
What is the difference between mass number and atomic mass?
Atomic Mass is the average of the masses of the existing isotopes in an element, but the mass number is the sum of the protons and neutrons in the nucleus of an atom.
What is the difference between the atomic number of an atom and it and mass number?
We make atomic number by number of protons in a atom. We make mass number by total of both protons and neutrons.
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
