No.
The mass number (also, nucleonic or atomic number) of an atom is equal to the total number of nucleons (the collective term for protons and neutrons) in its nucleus.
Isotopes are chemically near-identical atoms of an element that have the same number of protons and electrons, but a different number of neutrons.
There are several isotopes for each element, so the mass number of atoms from the same element will vary depending upon the number of neutrons they possess.
For instance:
Deuterium and tritium both have near-identical chemical properties to hydrogen, but the nucleus is different and heavier; deuterium and tritium weigh two and three times as much as hydrogen respectively.
Yes, atomic number = number of protons. Always.
Yes, it is true.
The atomic number of an element refers to the number of protons in the nucleus within the element. This is how the element is identified.
There are many different types of elements, all varying in the number of protons they contain. To determine the number of protons in a specific element, refer to the periodic table of elements. The atomic number (generally listed above the element's symbol, sometimes represented as 'Z') is equal to the number of protons in that atom.
We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single atom.
An atom's atomic number tells which element it is. The atomic number of an element is equal to its number of protons. The number of neutrons may vary within an element, giving rise to the concept of isotopes.
The Atomic Number of an element is equal to the number of Protons/Electrons in the nucleus and the Atomic Weight is approximately the total number of Protons/Electrons and Neutrons combined. Using Carbon as an example: Total Protons/Electrons = 6, therefore the Atomic Number is 6 Total Neutrons = 6, and the Atomic Weight is 12 Question? The Atomic Number of Lithium = 3 The Atomic Weight of Lithium = 7 How many Protons/Electrons? How many Neutrons? Answer: Protons/Electrons = 3 Neutrons = 4
The atomic number of an element refers to the number of protons in the nucleus within the element. This is how the element is identified.
The atomic number of an element is determined by the number of protons within it's nucleus.

The number of protons.
An atom's atomic number is the number of protons within the single atom of an element
The number of protons in an atom's nucleus is its atomic number. Each element has its own unique atomic number. An individual atom's atomic mass is the sum of the masses of the protons, neutrons, and electrons in the atom.
We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single atom.
If you know the atomic no. and atomic mass, then the no. of electrons, no. of protons and no. of neutrons can also be determined. Atomic No.=No. of electrons = No. of protons. No. of neutrons=Atomic mass-Atomic no. Also, by no. of electrons you can determine its valency and the no. of valence electrons.
An atom's atomic number tells which element it is. The atomic number of an element is equal to its number of protons. The number of neutrons may vary within an element, giving rise to the concept of isotopes.

The number of protons within an atom's nucleus can be determined by the atomic number as long as the atom is in its neutral state. Thus, 17 protons would be element 17 which is Cl.
it tells us the number on the periodic table and it also tells us how many protons and nuetrons and electrons are in the atom within the nuecles.
