It's what everything in this world is made up of. It makes up matter.
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
Atomic number is number of protons in an atom while atomic mass is the sum of protons and neutrons in an atom when you subtract you will get the number of neutrons in an atom.
No, an atom of aluminum and an atom of gallium do not have the same atomic mass. Aluminum has an atomic mass of approximately 26.98 atomic mass units, while gallium has an atomic mass of approximately 69.72 atomic mass units.
An atom's atomic number is the number of protons within the single atom of an element
The amount of protons in an atom is its atomic number
The atomic number of an atom is the number of protons in its nucleus.
The atomic number of an atom is the number of protons in its nucleus.
Proton + Nuetron = Atomic Mass
atomic number is how much protons(positive atom) and neutrons(neutral atom) are there in an element. therefore an atom does not have an atomic number
The atomic number of an atom is determined by the number of protons it has.
The atomic number of an atom is equivalent to the number of protons in its nucleus.
Atomic number = number of proton in an atom Thus atomic number of an atom with 11 protons is 11.
