Atomic Structure
The atom is the fundamental unit of matter and the basic building block of all chemical elements. It is composed of three subatomic particles: protons, neutrons, and electrons.
Protons and neutrons are located in the nucleus, which is the central part of the atom. Protons have a positive electric charge, while neutrons have no charge. Electrons orbit the nucleus in shells, or energy levels. Each shell can hold a specific number of electrons, and the outermost shell determines the chemical properties of the atom.
Arrangement of Electrons, Atomic structure worksheet answers key physical science
Electrons are arranged in shells and subshells. The first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and so on. Each subshell can hold a specific number of electrons, and the outermost subshell determines the chemical properties of the atom.
- s subshell:can hold up to 2 electrons
- p subshell:can hold up to 6 electrons
- d subshell:can hold up to 10 electrons
- f subshell:can hold up to 14 electrons
