The chemical formula of a compound shows the number of atoms of each element in the smallest unit of the compound. The smallest unit is a molecule for covalently bonded compounds and the minimum number of each of the right kinds of atoms to achieve electro-neutrality for ionically bonded compounds.
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
You think probable to the chemical formula of a molecule.
An empirical formula is a chemical formula which contain only the chemical symbol of elements; no number of atoms or structure.
To determine the total number of elements in a chemical formula, you count the atoms of each element present in the formula. Each element is represented by its chemical symbol (e.g., H for hydrogen, O for oxygen). The sum of the atoms of each element gives you the total number of elements in the chemical formula.
The chemical formula of a compound does not indicate the way that elements are joined in the compound. Chemical formulas tell you the identity of the elements in the compound and the relative proportions of the elements.
A molecule contain two or more atoms of chemical elements; each molecule has a specific formula.
A chemical formula shows the types and numbers of atoms in a compound. To read it, identify the elements and their respective numbers in the formula. The elements are represented by their symbols, and the numbers indicate the ratio of atoms in the compound.
A chemical formula shows the composition of a substance. It shows the elements present and their relative numbers. There are several types of formula which give specific types of information, but that's the basics.
a chemical formula is a force that holds atoms together in a compound.
The chemical formula of a compound provides information about the elements present in the compound and the ratio in which they are combined. The subscripts in the chemical formula indicate the relative number of atoms of each element in a compound.
It tells what elements are present in a molecule and how many atoms of each element are present.
I count four elements: calcium, hydrogen, phosphorus, and oxygen.
