Atomic Structure
www.ChemistryNotesInfo.com
The discovery of subatomic particles, including electrons, protons, and neutrons, led to a better understanding of atomic structure.
Electrons are negatively charged particles that orbit the nucleus of an atom.
Protons are positively charged particles that are located in the nucleus of an atom.
Neutrons are neutral particles that are also located in the nucleus of an atom.
The atomic number of an element is determined by the number of protons in its nucleus.
The mass number of an element is determined by the number of protons and neutrons in its nucleus.
The Bohr model of the atom proposed that electrons orbit the nucleus in specific energy levels.
The quantum mechanical model of the atom proposes that electrons exist in probability clouds around the nucleus.
The development of atomic models has led to a better understanding of chemical reactions and the behavior of matter.
Further research into atomic structure continues to expand our knowledge of the universe.
