In the standard notation of an element, the number at the top represents the atomic number. This atomic number indicates the number of protons found in the nucleus of an atom of that element, which also determines the element's identity and its position on the Periodic Table.

What is a number written below an element or atom called?
The number written below an element or atom is called its atomic mass. It represents the average mass of the element or atom, taking into account the different isotopes and their relative abundance.
What is a number written after an element that represents the number of atoms the element contains?
The number written after an element symbol that indicates the number of atoms of that element in a molecule is called a subscript. For example, in the chemical formula H₂O, the "2" is a subscript that indicates there are two hydrogen atoms for every one oxygen atom in the molecule. If no subscript is present, it is understood to be one atom of that element.

What is 110000 in standard form?
The number 110,000 in standard form is written as 1.1 × 10^5. In standard form, a number is expressed as a coefficient between 1 and 10 multiplied by a power of ten, which effectively represents its scale.
What is 200 million written in standard notation?
200 million written in standard notation is 200,000,000. This is done by placing eight zeros after the number 200. It represents two hundred million in numerical form.
