atomic number = number of proton in an element
number of proton = number of electron
mass number = number of proton + number of neutron
therefore...
atomic number = mass number - number of neutrons
atomic number or atomic weight. Subscript: atomic number, superscript: atomic weight: 94Pu239 or 239Pu
Argon Ar Atomic No 18 Atomic weight 39.948
Calcium iodide is CaI2.
No, an atom can only have one atomic formula, which is based on the number of protons it has in its nucleus. Each element on the periodic table is uniquely defined by its atomic number, which determines its atomic formula.
Rust is primarily composed of iron oxide, which has the chemical formula Fe2O3. Since iron (Fe) has an atomic number of 26 and oxygen (O) has an atomic number of 8, the atomic number for rust would be 26.
No. of neutrons=Atomic mass - Atomic number
atomic number or atomic weight. Subscript: atomic number, superscript: atomic weight: 94Pu239 or 239Pu
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.
atomic number or atomic weight. Subscript: atomic number, superscript: atomic weight: 94Pu239 or 239Pu
number of electrons
number of electrons
No, each element has a unique atomic formula based on the number of protons in its nucleus, which is called the atomic number. This atomic formula is represented by the element's chemical symbol.
Ammonium is a polyatomic ion, not an element and thus it does not have an atomic number. It is composed of nitrogen and hydrogen and has the formula NH4+. Nitrogen has the atomic number 7. Hydrogen has the atomic number 1.
