How is a formula of a compound written?
The formula of a compound is written using the symbols of the elements present in the compound and subscript numbers to represent the ratio of each element in the compound. The subscript numbers indicate how many atoms of each element are present in a molecule of the compound.
Why is the chemical symbol of a molecule of a compound also called the chemical formula of the compound?
The chemical symbol of a molecule represents the individual elements present in the compound, while the chemical formula shows the ratio of each element in the compound. The formula is essentially a written expression of the molecule's composition and structure, making it equivalent to the symbol in chemical representation.
What do the little numbers next to the letters in the formula of a molecule represent?
The little numbers next to the letters in the formula of a molecule represent the number of atoms of that element in the molecule. They indicate the ratio in which the elements are present in the compound.
The subscript in a chemical formula refers to the?
The subscript in a chemical formula refers to the number of atoms of that element present in the molecule. It is a small number written at the lower right of the element symbol. For example, in the formula H2O, the subscript 2 indicates that there are two hydrogen atoms in each water molecule.
A chemical formula used to show the number and types of atoms present in a molecule is referred to as what?
A chemical formula that shows the number and types of atoms in a molecule is known as a molecular formula. Molecular formulas are written by writing the symbol for each element followed by a subscript to show the actual number of atoms in the molecule.
What is the formula of the hydrogen atom?
the chemical formula of a hydrogen molecule is written H2 ( the 2 is meant to be small )
What does it mean if an atom has no subscript in a chemical formula?
There is one atom of that element in the molecule.
What does the 4 mean in the formula 4h20?
The "4" in the formula 4H₂O represents the number of water molecules present. Each water molecule is composed of two hydrogen atoms and one oxygen atom, written as H₂O. So 4H₂O means there are 4 water molecules in the compound.
How are formulas for ionic and covalent compounds written?
Formulas for ionic compounds are written by balancing the positive and negative charges of the ions to create a neutral compound. For covalent compounds, the subscripts in the formula indicate the number of atoms of each element present in the molecule.
What do subscripts represent?
Subscripts represent the number of atoms of an element in a molecule. They are written as small numbers to the right of the element symbol in a chemical formula. They indicate the ratio of elements in a compound.
How many atoms of hydrogen are present in NH42S?
The chemical formula for ammonium sulfide is written as (NH4)2S. In each molecule, there are 2x4=8 atoms of hydrogen.
What is the formula for hydrogen molecule?
Hydrogen is a diatomic element, so the formula would be H2.The chemical symbol is H, but hydrogen usually appears as H2.
