Three atoms of two elements.
The 2 in the compound H2O means that there are only 2 hydrogen atoms.simple as thatIt just means 2.it meansHydrogen, 2 oxygen.So it's basically just 2.H2o is actually just the scientific name for water, and it means 1 hydrogen atom, and 2 oxygen atoms.Hope that answers all your questions.Thanks! :)Incorrect, I'm afraid. it means 2 hydrogen atoms and one oxygen atom. It is a convention in chemistry to use capital letters.Its mean 2 parts of Hydrogen & One part of Oxygen.
Well if your talking about H2O, it means there is 2 hydrogen molecules and one oxygen.

In the formula H2SO4, there are 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms.
The elements in sulfuric acid (H2SO4) are hydrogen (H), sulfur (S), and oxygen (O).
In one molecule of H2SO4, there are 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms, making a total of 7 atoms.
The formula for a molecule with 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms is H2SO4, which represents sulfuric acid.
Number for hydrogen is +1.Number for sulphur is +6.Number for oxygen is -2.The oxidation number for the overall ion is -1. Oxidation numbers for hydrogen and oxygen are +1 and -2 respectively. By balancing the charges, the sulfur atom is in +6 state.
The subscripted number following an element tells you how many atoms of that element are in that molecule. H2SO4 -> (2) hydrogen atoms, (1) sulfur atom, and (4) oxygen atoms.
There are a total of 4 atoms in sulfur trioxide (SO3): 1 sulfur atom and 3 oxygen atoms.
To show that there are two hydrogen atoms and four oxygen atoms in sulfuric acid (H2SO4), the numbers are placed as subscripts next to the elements: H2SO4. This indicates that the ratio of hydrogen to sulfur to oxygen atoms in sulfuric acid is 2:1:4.
The oxidation number of hydrogen is +1, the oxidation number of sulfur is +6, and the oxidation number of oxygen is -2. In H2SO4, there are 2 hydrogen atoms (totaling +2), 1 sulfur atom (+6), and 4 oxygen atoms (totaling -8). The sum of the oxidation numbers should equal the charge of the compound, which is 0, so the oxidation number of sulfur in H2SO4 is +6.
A thiosulfate ion (S2O3^2-) consists of 3 oxygen atoms, 1 sulfur atom, and 2 hydrogen atoms for a total of 6 atoms.
There are 15 atoms in sulfuric acid (H2SO4): 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms.
Sulfuric acid, H2SO4, consists of 3 elements: hydrogen, sulfur, and oxygen.
