Nothing. The term "polyatomic atom" would mean an atom made up of two or more atoms and so is self-contradictory.
A polyatomic ion is a charge particle composed of multiple atoms covalently bonded together in much the same way as they are in molecules.
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
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.
The atomic number of an atom is the number of protons in its nucleus.
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.
No. Molecules do not have charge. Ions have a charge. If a compound is has more than one atom and a charge, then it is a poly-atomic ion, not a molecule.
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.
An atom's atomic number is the number of protons within the single atom of an element
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.
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.
Proton + Nuetron = Atomic Mass
The atomic number of an atom is the number of protons in its nucleus.
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.
