Atoms serve as the fundamental units of matter participating in chemical reactions. The chapter elucidates the internal structure of atoms, including the role of protons, neutrons, and electrons, as well as the formation of chemical bonds. It details atomic number, mass number, electron distribution in shells, and the practicality of valence electrons and valency in chemical bonding.
Atoms consist of electrons, protons, and neutrons.
The atomic number is the number of protons and determines the element, while the mass number is the total count of protons and neutrons.
Electrons are distributed in energy levels or shells around the nucleus, governed by rules such as the octet rule.
A negatively charged particle that orbits around the nucleus of an atom.
The combining capacity of an atom, determined by the number of electrons gained, lost, or shared.
A bond formed through the transfer of electrons from one atom to another, resulting in electrostatic attraction between oppositely charged ions.
A bond formed by the sharing of electrons between two non-metal atoms.
The total number of protons and neutrons in the nucleus of an atom.
