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
When elements combine to make a compound is it always in the same proportion?
No, the elements are not always in the same proportion. For example, two atoms of hydrogen combine with one atom of oxygen to make a single molecule of water. But one atom of hydrogen combines with one atom of fluorine to make a single molecule of hydrogen fluoride. The numbers of atoms involved depends on the number of electrons available in the outer electron clouds of the atoms involved.
Is aluminum a molecule?
Aluminum is not a diatomic molecule. As the term implies, a diatomic molecule is made up of only two elements which can either be the same or different.
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.
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.
The chemical formula for rubies is Al2O3. List the elements that combine to form a ruby and the number of atoms of each element in a single molecule of the gem?
Rubies are composed of aluminum and oxygen, with the chemical formula Al2O3 indicating that each molecule contains two aluminum (Al) atoms and three oxygen (O) atoms. Thus, in a single molecule of ruby, there are a total of 2 Al atoms and 3 O atoms.
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 in chemical formulas tells the number of atom in elements?
indicate the number of atoms or ions in a single unit
Does molecule mean a substance made up of only one kind of atom?
A molecule may consist of atoms of a single chemical element, as with oxygen (O2), or of different elements, as with water (H2O).
How many hydrogen elements are in a single molecule?
2
What is the mass of a single molecule of water?
- calculate the molecular mass of the substance from the atomic weights of the contained elements - 1 molecule gram of any substance contain 6,023 141 79.1023 molecules (Avogadro number) - mass of a single molecule is: Molecular mass in grams/Avogadro number
What is the atomic number for the atom?
We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single atom.
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

The numbers of atoms involved depends on the number of electrons available in the outer electron clouds of the atoms involved.
How many atoms are present in a single molecule 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.
