  • Alkaline Earth Metals

    Elements in group 2a known for forming basic solutions and remaining solid at high temperatures.
  • Beryllium

    A group 2a element that uncharacteristically forms covalent bonds by sharing electrons.
  • Magnesium

    A group 2a element that typically forms ionic bonds, such as with chlorine to form MgCl2.
  • Calcium

    A common alkaline earth metal in group 2a, known for its role in biological systems and ionic bonding.
  • Strontium

    A group 2a element similar to calcium, often used in fireworks for its red flame.
  • Barium

    A rare group 2a element, less abundant than others in its group.
  • Radium

    A radioactive group 2a element, making its behavior unpredictable.
  • Valence Electrons

    Electrons in the outer shell of an atom, crucial for bonding and chemical properties.
  • Effective Nuclear Charge

    The net positive charge experienced by valence electrons, influencing atomic bonding strength.
  • Metallic Bonding

    A type of chemical bonding characterized by a sea of electrons around metal atoms.
  • Ionic Bonds

    Chemical bonds formed through the transfer of electrons, typically between metals and nonmetals.
  • Covalent Bonds

    Chemical bonds formed by the sharing of electrons between atoms, often seen in nonmetals.
  • Periodic Table

    A tabular arrangement of elements, organized by increasing atomic number and recurring chemical properties.
  • Lewis Dot Structures

    Diagrams that represent the valence electrons of atoms within a molecule.
  • Octet Rule

    A chemical rule of thumb that reflects the tendency of atoms to prefer having eight electrons in their valence shell.
