Explanation of "Covalent Bond"
Definition: A "covalent bond" is a type of connection between two atoms in a molecule. In this bond, the atoms share a pair of electrons. This sharing allows the atoms to stick together, forming a stable structure.
Advanced Usage:
In more complex discussions, you might encounter terms like "polar covalent bond," which describes a type of covalent bond where the sharing of electrons is unequal, leading to a slight charge on the molecule.
Word Variants:
Covalent (adjective): Referring to the type of bond. For example, "covalent compounds" are substances made up of atoms connected by covalent bonds.
Covalently (adverb): Describes how atoms are connected. For example, "The atoms are covalently bonded."
Different Meanings:
In general usage, the term "bond" can also refer to a strong connection or relationship between people or ideas, but in chemistry, it specifically describes the connections between atoms.
Synonyms:
For "bond," you might find synonyms like "connection" or "link," but in the context of chemistry, "covalent bond" is a specific term with no direct synonym.
Idioms and Phrasal Verbs:
There are no common idioms or phrasal verbs specifically related to "covalent bond." However, you might hear phrases like "strong bond" in everyday language, which can refer to close relationships but does not have a direct connection to the scientific meaning.
Summary:
A covalent bond is when two atoms share electrons to stay together, forming molecules like water or carbon dioxide.
