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

∙ 14y agoThe atomic number of an element is equal to the number of protons in its nucleus. This value determines an element's unique identity on the Periodic Table.

∙ 11y agoThere is no need for a formula. The atomic number of an element is the same as the number of protons in the atom. e.g. chlorine has the atomic number 17 so its atom has 17 protons.
The number in front of a chemical formula is called a coefficient. It represents the number of molecules or formula units of each substance in a chemical reaction.
The chemical formula for argon is Ar. It is a noble gas with an atomic number of 18.
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
The number in front of a chemical formula is called a coefficient. It represents the number of molecules or formula units of each substance in a chemical reaction.
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
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.
The chemical formula for argon is Ar. It is a noble gas with an atomic number of 18.
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
