The number placed below an elements symbol in a chemical formula is called a what?
The number placed below an element's symbol in a chemical formula is called a subscript. Subscripts indicate the number of atoms of that element in a molecule.
What is a number written to the right of a chemical symbol?
a subscript Number of atoms of that element in the molecule.
What type of number after a chemical symbol tells how many atoms of that elements in a single molecule?
The number after a chemical symbol in a chemical formula represents the number of atoms of that element in a single molecule. This number is called a subscript, and it indicates the ratio of atoms in the compound.
The number to the lower right on an element symbol indication the number of atoms of that element?
The number to the lower right on an element symbol is the atomic number, representing the number of protons in the nucleus of an atom of that element. It does not indicate the number of atoms of that element in a compound; that information is conveyed through subscript numbers next to the element symbol in a chemical formula.
How would you write the chemical symbol for three molecules of oxygen that are each composed of two atoms of oxygen?
Three Oxygen molecules is called Ozone or O3.
The number placed below an elements symbol in a chemical formula is called a what?
The number placed below an element's symbol in a chemical formula is called a subscript. Subscripts indicate the number of atoms of that element in a molecule.
what number represents the subscript in the formula shown?
The letter or letters that represent an element are called its atomic symbol. The numbers appearing as subscripts in the chemical formula indicate the number of atoms of the element immediately before the subscript. If no subscript appears, one atom of that element is present.
What is a number written to the right of a chemical symbol?
a subscript Number of atoms of that element in the molecule.
The small number used to represent the number of ions of a given element in a chemical formula?
The small number used to represent the number of ions of a given element in a chemical formula is called a subscript. Subscripts are written to the right of the element's symbol and indicate the number of atoms or ions present.
In a chemical formula what is used to indicate the number of atoms of each element?
It is called a subscript. For example: In the formula for water (H2O), 2 is the subscript indicating that there are 2 hydrogen atoms in the compound .
What type of number after a chemical symbol tells how many atoms of that elements in a single molecule?
The number after a chemical symbol in a chemical formula represents the number of atoms of that element in a single molecule. This number is called a subscript, and it indicates the ratio of atoms in the compound.
In the chemical formula for magnesium chloride what is the number 2 called and what does it tell you?
subscript

What is the number in front of a chemical formula called-?
atomic number or atomic weight. Subscript: atomic number, superscript: atomic weight: 94Pu239 or 239Pu
In chemistry what is the meaning of subscript?
A subscript looks like this Subscripts are numbers used to tell you how many atoms of an element are present in the equation; for instance: * water H20 has 2 atoms of hydrogen and one of oxygen * glucose C6H12O6 has 6 atoms of carbon, 12 of hydrogen, and 6 of oxygen The large numbers put in front of an equation, either to balance it, or simply to tell you how many molecules there are, is called a coefficient; e.g. in 2H2O , the first '2' is the coefficient, & means that all the atoms following it have to be multiplied by that number - so in 2H2O there are 4 atoms of H, and 2 atoms of 0
