Study Notes
Fundamental Concepts of Atoms
- An atom is the smallest basic unit of matter and is essential for all forms of life.
- Elements are unique types of atoms that cannot be further broken down by ordinary chemical means.
- A compound is formed when two or more different elements bond chemically, resulting in a new substance.
Chemical Interactions
- An ion is an atom that has gained or lost electrons, resulting in a net electrical charge, which can be either positive or negative.
- Ionic bonds occur when positively and negatively charged ions attract each other through electrical forces, leading to the formation of stable compounds.
- A covalent bond forms when two or more atoms share pairs of electrons, allowing them to achieve greater stability.
Structural Elements
- A molecule consists of two or more atoms connected by covalent bonds, representing the simplest form of a compound.
