The atomic number of an atom indicates the number of protons that the atom has.
All atoms contain protons, neutrons and electrons. (The exception is hydrogen which has only one proton and one electron). It is the number of protons that defines the element. So, helium with an atomic number of 2 will always have 2 protons.
Normally, the atom will have the same number of electrons as protons but there are many instances where this is not the case.
The number of neutrons can vary in some atoms. Let us take carbon as an example: It has an atomic number of 6 so it has 6 protons and 6 electrons. Most carbon atoms have 6 neutrons but a very small number have 8 neutrons. Although they are the same element, they are two different isotopes known as carbon 12 and carbon 14.
The Atomic Mass of an element is approximately the mass of each proton, neutron and electron added together.
What else can I help you with?
Does the number of electrons in an atom give its atomic number?
The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.
The number of protons and neutrons in an atom?
Depends on the atom. The atomic number will give you the number of protons. The atomic weight will give you approximately the number of protons and neutrons combined.
Does number of electrons in an atom give it atomic number?
Yes, the number of electrons in an atom is equal to its atomic number. The atomic number is the number of protons in the nucleus of an atom, and since atoms are electrically neutral, they have the same number of electrons.
How many atoms in PVC?
We make atomic number by number of protons in a atom. PVC is not single atom. We cant give it a atomic number.
What is the atomic number of an atomic indicate?
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
Does the number of electrons in an atom give its atomic number?
The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.

What do Protons give to an atom?
Number of protons = the atomic number of the element
What is the atomic number of an atomic indicate?
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
What is atomic mass number minus protons?
atomic mass number - protons = number or neutrons
When you subtract the atomic number from the atomic mass it will give you the number of what?
the protrons, neutrons and electrons in a atom
How can you solve of number of neutrons?
You can determine the number of neutrons in an atom by subtracting the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). This will give you the number of neutrons in the atom.
The protons and neutrons in an atom add up to give the atom's?
Mass number/Atomic Mass
What is the atomic number of an atom determained by the number of what?
The atomic number of an atom is determined by the number of protons it has.
What is atomic number of an atom is?
The atomic number of an atom is the number of protons in its nucleus.
