What is a substance called with a covalent bond?
covalent compound
When atoms of different elements form covalent bonds, a new substance, called a covalent compound, results. A molecule is the smallest particle of a covalent compound that still has the properties of the compound.
What are covalent bonded substances made up of?
Structure of Organic Compounds A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei.
What type of molecules have covalent bonds?
Covalent bonds are commonly found in carbon-based organic molecules, such as our DNA and proteins. Covalent bonds are also found in inorganic molecules like H2O, CO2, and O2. One, two, or three pairs of electrons may be shared, making single, double, and triple bonds, respectively.

What are covalent bonds quizlet?
Covalent Bonds. A bond formed between atoms where electrons are shared. It happens between atoms of nonmetals. Molecule. The smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms held together by chemical forces.
What is a covalent bond example?
Water (H2O) A water molecule consists of two hydrogen (H) and one oxygen (O) atoms. Oxygen has a valency of two, and hydrogen has only one electron in its orbital. So, each hydrogen atom will share its electron and covalently bond with the oxygen. As a result, there will be two single bonds.
How do you name covalent compounds?
Rules for naming simple covalent compounds:
- Name the non-metal furthest to the left on the periodic table by its elemental name.
- Name the other non-metal by its elemental name and an -ide ending.
- Use the prefixes mono-, di-, tri-…. to indicate the number of that element in the molecule.
What is meant by the term covalent bonding?
A covalent bond is a shared pair of electrons. Covalent bonding results in the formation of molecules or giant structures. Substances with small molecules have low melting and boiling points and do not conduct electricity.
What kind of molecules are formed by covalent bonds?
Substances with covalent bonds often form molecules with low melting and boiling points, such as hydrogen and water. The slideshow shows a covalent bond being formed between a hydrogen atom and a chlorine atom, to form hydrogen chloride.
How is a covalent bond a chemical attraction?
A covalent bond is a chemical attraction that involves the sharing of which of the following particles between two atoms? In a reaction that forms an ionic bond, one atom must have an unfilled outer shell that can accept electrons, while the other atom must have which of the following?
How are atoms joined together in a chemical bond?
Atoms can join together by forming a chemical bond, which is a very strong attraction between two atoms. Chemical bonds are formed when electrons in different atoms interact with each other to make an arrangement that is more stable than when the atoms are apart.
What kind of bond is made by electron sharing?
The bond made by electron sharing is called a covalent bond. Covalent bonding and covalent compounds will be discussed in Section 4 “Covalent Bonding and Simple Molecular Compounds”.
