Chemical bonds are forces that hold atoms together to form molecules or compounds. These bonds form when electrons are shared or transferred between atoms, creating stable arrangements.
Figure 1: Visualization of different types of chemical bonds
There are three primary types of chemical bonds:
Ionic bonds form between metals and non-metals. In this type of bond, electrons are completely transferred from one atom to another, creating positively charged ions (cations) and negatively charged ions (anions).
For example, when sodium (Na) and chlorine (Cl) form an ionic bond, sodium loses an electron to become Na⁺, and chlorine gains that electron to become Cl⁻, forming sodium chloride (NaCl) or table salt.
Which of the following best describes an ionic bond?
Covalent bonds form between non-metals. In this type of bond, atoms share electrons to achieve a stable electron configuration. Covalent bonds can be single, double, or triple, depending on how many pairs of electrons are shared.

Sarah Johnson
I'm trying to understand the mechanism of enzyme catalysis better. Can someone explain how enzymes lower activation energy and what factors can inhibit enzyme function?
Michael Chen
I'm studying nuclear physics and I'm confused about the energy release mechanisms in fusion vs. fission reactions. Could someone explain the key differences and why fusion is more challenging to achieve on Earth?
