What type of number after a chemical symbol tells how many atoms of that element are in a single molecule?
A+...subscript.
That is the subscript in a chemical formula. For example, oxygen by itself in a jar is usually diatomic (except for ozone, but that doesn't last long in standard temperatures and pressures) so its molecular formula is O2, and so is hydrogen H2, water molecule has one oxygen bonded to two hydrogen H2O, so when we write the formula for making water it has to take into account that each molecule of oxygen forms two molecules of water which needs two molecules of hydrogen (remember the least common multiple stuff we went through in grade school?) and the energy it has to take from its immediate viscinity
O2 + 2H2 + ΔE = 2H2O
keeping in mind that most formulas don't include the unusual things, like a mole of oxygen will have a very small amount of single oxygen molecules and some ozone, but they don't last long enough to be useful, and they are usually in small enough amounts that scientists use the ever present phrase "small enough to be ignored"

Is iron chloride an element?
No, iron chloride is not an element. Iron chloride is a chemical compound composed of the elements iron and chlorine. Iron is the element with the atomic number 26 and symbol Fe, while chlorine is the element with the atomic number 17 and symbol Cl.
What shows the types and numbers of atmos joined in a single molecule of a molecular compound?
The chemical formula of a molecular compound provides information about the types and numbers of atoms that are joined in a single molecule. Each element in the formula represents the type of atom present, and the subscript numbers next to them indicate the number of atoms bonded together in a single molecule. Additionally, the way atoms are arranged within the molecule can also provide clues about their connectivity.
Is iodine a mixture?
No, iodine is not a mixture. Iodine is a chemical element with the symbol I and atomic number 53. It exists as a single substance with a distinct molecular structure.
Is F2 an element or a compound?
F2 is an element. It's the diatomic form of fluorine, a highly reactive and toxic gas that you definitely don't want to mess with. So, in conclusion, F2 is an element, not a compound. Stay safe and don't go huffing fluorine gas!
How many hydrogen atoms are in the molecule of C8H10N4O2?
The subscripts in a chemical formula representing a single molecule, are the numbers of atoms of each atom in one molecule (remember no subscript is understood to be 1. So add the subscripts to get the total number of atoms in one molecule of a substance. 8+10+4+2=24 atoms in a single molecule of C8H10N4O2.
What type of number after a chemical symbol tells how many atoms are in a single molecule?
The subscript, the little number below and after the element, tells how many atoms are in a single molecule.
What type of number after a chemical symbols tells how many atoms of that element are in single molecules?
The subscript number after a chemical symbol indicates how many atoms of that element are present in a single molecule of the compound.
What type of number after a chemical symbol tells how many atoms of that of that element are in a single molecule?
It is the subscripted number immediately after the chemical element symbol in the molecular formula. If there is no number, then only one atom of that element is in itExample:H2O means two H's plus one O in water,NH3 = one N and three H atoms in ammonia
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.
Is helium a compound molecule?
Helium is a chemical element, not a compound; also helium is monoatomic.
Is carbonate non polar?
Chemical Polarity refers to the separation of electrical charge within a single molecule composed of chemical elements. Carbon is a chemical element not a molecule.
Is sodium an atom or molecule?
Sodium is an atom. It is a chemical element with the symbol Na and atomic number 11. Sodium exists as single atoms and does not naturally occur as a molecule in its elemental form.
What is the subscripts of a chemical equation?
The amount of atoms of each element that make up a single molecule.
What type of number after a chemical symbol chemical symbol tells how many atoms of that element are in a single molecule?
It is the subscripted number immediately after the chemical element symbol in the molecular formula. If there is no number, then only one atom of that element is in itExample:H2O means two H's plus one O in water,NH3 = one N and three H atoms in ammonia
What is the atomicity of an element?
The atomicity of an element refers to the number of atoms present in a single molecule of that element. For example, oxygen has an atomicity of 2 because its molecule contains 2 oxygen atoms (O2), while helium has an atomicity of 1 since it exists as single atoms (He).
What type of number after chemical symbol tells how many Atoms of that element in a single molecule?
The subscript that is to the right of the element symbol, no subscript means 1. Example H2O, 2 hydrogen 1 oxygen
What type of number of after a chemical symbol tells how many atoms of that element are in a single molecule?
It is the subscripted number immediately after the chemical element symbol in the molecular formula. If there is no number, then only one atom of that element is in itExample:H2O means two H's plus one O in water,NH3 = one N and three H atoms in ammonia
