2 ημέρες πριν · A chemical bond is an interaction that holds molecules and compounds together by the sharing or exchanging of electrons. When an atom comes into proximity to another atom and its valence (outer) electrons are attracted to the positive (nuclear) charge of the other atom, a bond between the two atoms can be formed.
Definition: What is a Chemical Bond? Chemical bonds are forces that hold the atoms together in a molecule. They are a result of strong intramolecular interactions among the atoms of a molecule.

Covalent bonds form between the elements that make up the biological molecules in our cells. Unlike ionic bonds, covalent bonds do not dissociate in water. Interestingly, chemists and biologists measure bond strength in different ways.
Objectives. After this chapter, you should be able to. interpret the properties of elements that are important for life from the periodic table. understand why and how atoms form bonds. draw Lewis dot and line structures to represent chemical bonds. What is life? Why is an elephant alive but a table inert?
Chemical bonding is the general term used to describe the forces that hold atoms together in molecules and ions. Three idealized types of bonding are ionic bonding , in which positively and negatively charged ions are held together by electrostatic forces, covalent bonding , in which electron pairs are shared between atoms and metallic bonding ...
According to Lewis Theory, a chemical bond is formed when the bonding atoms share or transfer electrons to achieve a stable electronic configuration. An ionic bond is formed if electrons are completely transferred, as in the case of a reaction between a metal and a nonmetal.
