The atomic number is the number of protons in the nucleus of an atom of any given element. The mass number is the number of protons and neutrons in the nucleus of an atom of an isotope of an element.
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)
The isotopes of the same element has the same atomic number. But the mass number (atomic mass) is different.
The mass number is the sum of neutrons and protons in the atomic nucleus and is different for each isotope of any element. For example the isotope oxygen-16 has the mass number 16. The atomic weight of oxygen (not Atomic Mass) is [15,99903; 15,99977] after the IUPAC Tables - 2009. The atomic number of oxygen is 8.
Number of neutrons = Mass number - atomic number
Atomic number of an element is the number of protons that an atom of an element contains. The atomic weight (the mass of the atom) is measured by not only the mass of the proton(s), but by the mass of the nuetrons and electrons too.
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.
No it is not the atomic number. We call it mass number.
the atomic mass is the number of protons and neutrons in an atom of an element and the atomic number is the number of protons of an atom of an element.
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.
Atomic mass and atomic number are two different things. Atomic mass is the mass of an atom compared to that of hydrogen. The atomic number is the atom's position in the periodic table. It's also the number of protons it has.
Those are different facts. atomic number is total of protons and neutrons.
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
The atomic mass is an average, allowing for the relative abundances of different isotopes.
mass number = number of protons + number of neutrons DIFFERENT FROM ATOMIC MASS atomic mass = weighted average of all the isotopes of that element
Number of neutrons = Atomic mass - Atomic number Atomic number of neon: 10 Atomic mass: depending on the neon isotope, each isotope has a different mass
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.
