A number written to the left of a chemical symbol or formula is called?

In chemical symbol, number written on top-left (2H) is is the mass number, and on the bottom left (1H) is atomic number. In chemical symbol the number in the very left of formula is used for balancing chemical equation.


What is the number left over in division called?

The number left over in division is called the remainder.


What is The number left after a whole number is divided equally?

This number, which is left after a whole number is divided equally, is usually called the remainder. This number can be written as a whole number (6 R1), as a fraction (1/2 if you were dividing by 2 to begin with), as well as a number of other ways.


A number placed in front of a chemical formula in a chemical equation is called?

In a chemical Equation ,The reactants are on the left side of a chemical equation and the products are on the right side.The number in front of a chemical formula in a chemical equation is called atoms. They should be a balancing number on both the sides.


What is written in front of the formula used to balance chemical equations?

The reactants are written on the left side of the equation, while the products are written on the right side. The equation is balanced by adjusting the coefficients in front of the chemical formulas so that the number of atoms for each element is the same on both sides.


What number do you place to the left of the formula for a substance taking part in a reaction?

The number placed to the left of a formula in a chemical equation is the coefficient, which represents the stoichiometry or the ratio of moles of each substance involved in the reaction.


Which one of the following is the number you place to the left of the formula a substance taking part in a reaction?

The number you place to the left of a formula in a chemical equation is the coefficient, which represents the amount of that substance taking part in the reaction.

What is a number left over called?

Your question isn't fully clear, but if you are referring to the process of division of numbers, the "number left over" is called a remainder.


What is the number to the left to a chemical formula?

Balancing a chemical equation can often require a whole-number coefficient placed in front of a chemical formula. This upholds the Law of Conservation of Matter, which says that matter cannot be created or destroyed. These coefficients must be in the lowest possible ratio.


What is the number called that is left over after one number is divided into another number?

The remainder.


What is the small written beneath an element symbol called?

I assume you mean the small numbers written under the letters that are the element symbol. The one on the bottom left is the "Atomic Number" and is the number of Protons in the nueclus of the atom, this is what makes an element unique. 1H indicates that Hydrogen has only one proton and is "Atomic Number" one, these numbers are not normally written in unless it's relevent to whatever is being discussed. If the symbol is in a formula for a more complex molecule then there might be a number on the bottom right of a symbol - this is an indication of how many of this atom are in the molecule. so Water is H2O the two indicating there are two hydrogens in the structure. There are also numbers above, on the left the "Atomic Mass" being the total number of Protons and Neutrons in the element. Top right being the "Charge" if any (this would make it an Ion)
