What chemical bond occurs when atoms share electrons?
covalent bond
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. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
What is a chemical bond between atoms?
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. In general, strong chemical bonding is associated with the sharing or transfer of electrons between the participating atoms.
What is chemical bond involves sharing electrons?
A chemical bond formed by sharing a pair of electrons is called a covalent bond. The diatomic hydrogen molecule (H 2) is the simplest model of a covalent bond, and is represented in Lewis structures as: The shared pair of electrons provides each hydrogen atom with two electrons in its valence shell (the 1s) orbital.
What are 5 types of chemical bonds?
The electrical forces, called chemical bonds, can be divided into five types: ionic, covalent, metallic, van der Waals, and hydrogen bonds.
What do electrons have to do with chemical bonds?
The electrons that participate in chemical bonds are the valence electrons, which are the electrons found in an atom’s outermost shell. When two atoms approach each other these outer electrons interact. Electrons repel each other, yet they are attracted to the protons within atoms.
What are bonds involve sharing of electrons?
4 Types of Chemical Bonds Ionic bond. Ionic bonding involves a transfer of an electron, so one atom gains an electron while one atom loses an electron. Covalent bond. The most common bond in organic molecules, a covalent bond involves the sharing of electrons between two atoms. Polar bond. Hydrogen bond.
