What is the formula for Ca and I?
Calcium iodide is CaI2.
Is it possible for an atom to have more than one atomic formula?
An element can have a number of isotopes with different atomic mass but will always have the same atomic number. Some elements can also form two or more allotropes that can have different molecular formulas, for example oxygen can be O2 or O3.
What is the atomic number for rust?
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.

atomic number or atomic weight. Subscript: atomic number, superscript: atomic weight: 94Pu239 or 239Pu
Is it possible for an element to have more than 1 atomic formula?
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.
What is the formula for atomic mass?
number of electrons
What is Formula for atomic mass?
number of electrons
What is the atomic number of ammonium?
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.
What is the formula of argon?
Argon Ar Atomic No 18 Atomic weight 39.948
What is the formula for the atomic number?
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
What is the formula for Ca and I?
Calcium iodide is CaI2.
