What must combine chemically to form molecules?

What must combine chemically to form molecules?

When atoms combine by forming covalent bonds, the resulting collection of atoms is called a molecule. We can therefore say that a molecule is the simplest unit of a covalent compound.

What is chemically combined called?

May 13, 2017. A combination of two or more elements chemically combined is a compound .

Is a molecule chemically combined?

A molecule is formed when two or more atoms of an element chemically join together. If the types of atoms are different from each other, a compound is formed. Water is also a molecule because it is made from atoms that have been chemically combined.

What is two or more elements chemically combined make up a?

Elements can be chemically combined into compounds, therefore, a compound consists of two or more elements combined, in definite proportions, by chemical means. Compounds may be formed by combining atoms of their constituent elements by ionic bonds or by covalent bonds.

What are chemical molecules?

molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.

How are two elements combined to form a chemical compound?

Two or more elements combined into one substance through a chemical reaction, such as water, form a chemical compound. All compounds are substances, but not all substances are compounds. A chemical compound can be either atoms bonded together in molecules or crystals in which atoms, molecules or ions form a crystalline lattice.

What do you call a mixture of two chemicals?

Mixtures vary by composition. Homogenous (evenly-distributed) mixtures of two or more chemicals are called solutions. Salt water is a solution, Italian dressing is not (because the ingredients do not dissolve completely). Mixtures of metals are called alloys (bronze is an alloy of copper and tin)

What are compounds made of carbon and hydrogen called?

Compounds made primarily of carbon and hydrogen atoms are called organic compounds, and all others are called inorganic compounds. Compounds containing bonds between carbon and a metal are called organometallic compounds. Chemical substances are often called ‘pure’ to set them apart from mixtures.

How are electrons shared in a molecular compound?

In a molecular compound, the electrons of the elements making it up are shared, forming covalent bonds. The smallest particle of a molecular compound that has the properties of that compound is a molecule. In an ionic compound, atoms lose or gain electrons and form positive or negative ions.
