Oxygen and Hydrogen, along with Fluorine, Chlorine, Bromine, Iodine, and Nitrogen, to not exist naturally as single atoms. O2 stands for an oxygen molecule, which is made up of two oxygen atoms bonded together. H2 stands for two Hydrogen atoms bonded together. Sometimes atoms are bonded together for other reasons. This notation means the same no matter what the element. For example, Ca2 would stand for two calcium atoms bonded together.

How many elements are present in h2o?
H2S contains two elements: hydrogen and sulfur.
Explain the number and kinds of atoms in the formula H2O2?
The formula H2O2 represents hydrogen peroxide, which consists of two hydrogen atoms and two oxygen atoms. The ratio of hydrogen to oxygen atoms is 2:2, indicating that there are equal numbers of each atom in the molecule.
What does the O in H2O stand for?
The O in H2O stands for oxygen. The H represents hydrogen, and the supbscripted 2 shows that there are 2 hydrogen atoms.
Why do both oxygen and hydrogen have subscripts of 2?
Oxygen and hydrogen have subscripts of 2 in the chemical formula for water (H2O) because they combine in a ratio of 2:1 to form a stable compound. Each water molecule contains two hydrogen atoms and one oxygen atom.
How do you get a small 2 and 4 in H2SO4?
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.
What is a subscript and where is it located in a chemical formula?
In a chemical formula, a subscript is a number written to the right and slightly below the symbol for the chemical element. If the subscript is 1, it is not written. The subscripts for the chemical formula for water, H2O, are 2 for hydrogen and 1 for oxygen. The subscripts for the chemical formula for glucose, C6H12O6, are 6 for carbon, 12 for hydrogen, and 6 for oxygen.
How many atoms in 2H2o2?
4 2 hydrogen and 2 oxygen
What is the subscripts for h2?
The subscript for Hâ‚‚ is 2, indicating that there are two hydrogen atoms present in the molecule.
What do subscripts in chemical equations tell about the equation?
The subscript in the equation tells you how many atoms of that element there are in the reaction. For example: H20 --> H2 + O2 Before the reaction there are 2 hydrogen atoms and 1 oxygen (the subscript 1 isn't shown). After the reaction there are 2 hydrogen atoms and 2 oxygen atoms. Keep in mind that this is a skeleton equation and isn't balanced yet.
What do subscripts in a chemical formula indicate?
Subscripts indicate the number of the preceding element Ie. in H2O there are two hydrogens (H) and one oxygen (O) or in C6H12O8 there are six carbon (C) twelve hydrogen (H) and eight oxygen (O) The number of atoms of the same element in the molecule
What is in H2O?
2 hydrogen, one oxygen oxygen and hydrogen (2) Henceforth, H2O.
What are the names of the elements in Hydrogen peroxide?
The elements in hydrogen peroxide are hydrogen and oxygen.
What do subscripts tell you about a compound?
This is farely simple. The subscripts just tell you how many atoms of an element are in the compund. Like this: H20 - Water has 2 hydrogen atoms and 1 oxygen atom CO2 - Carbon Dioxide has 1 carbon atom and 2 oxygen atoms. hence the name carbon di(which means 2)oxide(oxygen). The numbers succeeding elements indicate the number of atoms of that particular element in the compound. For example, in H20, there are two hydrogen atoms and one oxygen atom. In H2SO4, there ar two Hydrogen atoms, one Sulfur atom and four Oxygen atoms.
What is the point of subscripts in writing chemical formulas?
The point is to show the number of atoms of each element. However these are not the exact numbers. There are as many atoms, which could be zillions, that extend to the end of the element. They are instead in the lowest whole number ratio. For example, there are not 2 hydrogen atoms and 1 oxygen atom in water. There may be 200000000 hydrogen and 100000000 oxygen, but it simplifies to the lowest whole number ratio of 2 hydrogen and 1 oxygen. Hope that helped.
What are the chemical formulas for water and hydrogen peroxide?
The chemical formula for water is H2O, meaning it has two hydrogen atoms and one oxygen atom. The chemical formula for hydrogen peroxide is H2O2, indicating it has two hydrogen atoms and two oxygen atoms.
