The number of atoms of each element present in the molecule is indicated by what?
The number of atoms of each element present in a molecule is indicated by the subscript to the right of the element symbol in the chemical formula. For example, in H2O, there are 2 hydrogen atoms and 1 oxygen atom.
Why does the oxygen symbol O not have a subscript?
Because symbols for the elements do not have subscripts. A subscript is added in the chemical formula of a compound to indicate how many atoms of the element are included in a molecule of the compound. For example, when hydrogen (H) and oxygen (O) combine to form water (H2O), a subscript 2 is added to the H to indicate there are two hydrogen atoms in a molecule of water, but no subscript is added to the O, because there is only one oxygen atom is in a molecule of water.
How many total atoms are found in one molecule of H2O?
One molecule of H2O contains a total of three atoms: two hydrogen atoms and one oxygen atom.
How many different elements are in the formula H2O?
Only two different elements. Hydrogen and Oxygen
What does the subscript 2 in H20 mean?
How many atoms of Hydrogen (since "H" stands for 'Hydrogen') is in water (in this case). not sure if this is your question but there are 2 hydrogen and on oxygen.hope i can help
What is the number 2 in the formula for hydrogen called?
H2O The little 2 is a subscript that tells you that there are 2 Hydrogen atoms in the compound. There is no 1 after the Oxygen because if there is no subscript, there is an understood 1 atom in the compound.
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.
What does The subscript in a chemical formula refers to the?
The subscript refers to the amount of atoms of that element in the formula e.g. H2O means two atoms of hydrogen and one atom of oxygen in one molecule of water. Hope this helps.
What does subscript in a chemical formula refer to?
The subscript refers to the amount of atoms of that element in the formula e.g. H2O means two atoms of hydrogen and one atom of oxygen in one molecule of water. Hope this helps.
Can you give a sentence for the word subscript?
The subscript in the molecular formula of water, H2O, says that there are two atoms of hydrogen for every one atom of oxygen.
What do you do if there is only one atom of an element in a formula?
You do not write a subscript because it is understood to be one. For example, the formula for water, H2O, indicates that there are two hydrogen atoms and one oxygen atom in a molecule of water. There is no subscript written next to the oxygen atom because it is understood to be one.
What is the subscript is the chemical expression of dihydrogen oxide?
The chemical formula of dihydrogen oxide is H2O. This means that the subscript for hydrogen in this chemical expression is 2.
What does the subscript in a chemical refers?
The subscript refers to the amount of atoms of that element in the formula e.g. H2O means two atoms of hydrogen and one atom of oxygen in one molecule of water. Hope this helps.
What does the subscript in a chemical refer to?
The subscript refers to the amount of atoms of that element in the formula e.g. H2O means two atoms of hydrogen and one atom of oxygen in one molecule of water. Hope this helps.
Does the 2 mean How many hydrogen atoms are in a molecule of water?
Yes. In the chemical formula H2O, the subscript 2 after the hydrogen means there are two hydrogen atoms in a molecule of water. The absence of a subscript after the oxygen means the subscript is understood to be 1, so there is one atom of oxygen in a water molecule.
How many subscripts does the formula for water have?
The formula for water is H2O, the single subscript is the number 2.
What does the subscript mean in the chemical formula?
usually a subscript denotes the number of atoms of a particular element within the formula. ie H2O (the 2 would be a subscript) indicates there are two atoms of hydrogen in one molecule of water.
