the cation (metal) calcium (charge 2+) gives its valence electrons to the anion (nonmetal) oxygen (charge 2-) to create an ionic bond between the elements calcium and oxygen, named calcium oxide (:
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.
When you combine the elements K (potassium) and Cl (chlorine), you get potassium chloride (KCl), a compound commonly used as a salt substitute and in medical treatments.
A compound is a substance made up of two or more different elements chemically bonded together. Compounds are formed through chemical reactions where atoms from different elements combine to form molecules with specific properties and characteristics. The bonding can be ionic (transfer of electrons) or covalent (sharing of electrons) depending on the types of elements involved.
The formula of a compound shows the ratio of elements present in the compound. This is helpful in understanding the chemical structure and properties of the compound. It also allows for predicting how different elements will combine to form new substances.
Compounds are represented in a formula unit to show the ratio of atoms present in the compound. This helps in identifying the elements involved and their quantities in a simple and concise manner. The formula unit provides information on the chemical composition of the compound.
Magnesium, sulfur, and oxygen
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.
The empirical formula of a compound represents the simplest whole-number ratio of the elements present in the compound. It does not necessarily reflect the actual number of atoms of each element in the molecule, but it provides the relative proportions of the elements in the compound.

a chemical formula
A chemical compound is represented by a specific combination of chemical elements bonded together in a specific ratio. This combination is represented by a chemical formula that shows the type and number of atoms of each element in the compound.
Compounds are represented in a formula unit to show the ratio of atoms present in the compound. This helps in identifying the elements involved and their quantities in a simple and concise manner. The formula unit provides information on the chemical composition of the compound.
The ionic formula for aluminum is Al3+ and for selenium is Se2-. When these two ions combine, the formula for the resulting ionic compound is Al2Se3.
A chemical formula is a combination of symbols that shows the ratio of elements in a compound. Each element is represented by its chemical symbol, and the subscripts indicate the relative number of atoms of each element in the compound.
A compound is a substance composed of two or more elements in a fixed ratio. The elements in a compound are chemically bonded together, creating a new substance with unique properties different from its constituent elements. The ratio of elements in a compound is represented by its chemical formula.
