Atomic structure

• Neutrons have no charge and are also located in the nucleus.
• Protons are positively charged particles found in the nucleus.
• The nucleus is the central part of an atom, containing protons and neutrons.
• Protons have a positive charge, electrons have a negative charge, and neutrons have no charge.
• The number of protons determines the element's identity (atomic number).
• Electrons are negatively charged particles that orbit around the nucleus at different energy levels.
• The number of protons determines the element, while the number of neutrons can vary to form isotopes.
• Atoms can gain or lose electrons to form ions with positive or negative charges.
• Ions can be formed by gaining or losing electrons from atoms.
• who came up with the current atomic theory?

  Erwin Schrodinger, The quantum model
• What is the current atomic theory?

  Electrons don't move around the nucleus in "circular" orbits but exist in clouds or orbitals where their positions is uncertain
• Negatively charged electron cloud containing electrons
• protons and neutrons are known as nucleons and each have almost identical mass
• electrons have 1/1800th the mass of a proton
• When opposite charges attract it is known as electrostatic attraction
• Electrostatic attraction of the atom's electrons to the protons within the nucleus keeps the atom bound together
• Every atom is given a profile with unique details called a chemical symbol
• What is the definition of an isotope?

  Atoms of the same element that have different numbers of neutrons but the same number of protons and electrons
