Atom

Atoms are the fundamental units of matter, composed of protons, neutrons, and electrons. The number of protons determines the element, while atoms can bond to form molecules and are primarily empty space. Typically, the number of electrons equals the number of protons, resulting in an electrically neutral atom.

Atoms are the basic building blocks of matter.

They are the smallest units of an element that still


retain the element’s chemical properties. Each atom consists of three main subatomic particles:
1. Protons – positively charged particles found in the nucleus.
2. Neutrons – neutrally charged particles also found in the nucleus.
3. Electrons – negatively charged particles that orbit the nucleus in electron shells.
Key points about atoms:
 The number of protons defines the element (e.g., carbon has 6 protons).
 Atoms are mostly empty space.
 Atoms can bond with each other to form molecules.
 The number of electrons usually equals the number of protons, making the atom
electrically neutral.
