SCI Q2 REVIEWER

• sharp (s) orbital It is a spherical cloud that becomes less in density as the electron creates a greater distance from the nucleus
• Orbital is a region around the nucleus of an atom
• Electron configuration is a shorthand representation of how electrons are located within orbitals, levels, and sublevels.
• Pauli Exclusion Principle this principle states that only a maximum of two electrons can occupy an orbital, and an excess of two is excluded
• Hund's Rule this states that for a set of orbitals, one electron must fill up each orbital until all the orbitals contain one electron with parallel spin.
• Ground state the lowest energy level or energy state that an electron normally occupies
• Excited state the highest energy state farthest from the nucleus
• Quantum numbers are used to describe the position and energy of electrons in an orbit
• Ionization Energy the energy needed to remove an electron from the neutral atom
• Ductility is the ability of metals to be drawn into a wire
• Luster is the ability to shine and and reflect light
