Termini in questo insieme (14)

  • Bond Angle
    Angle formed by two neighboring atoms with a central atom between them, crucial for determining molecular shape.
  • Central Atom
    Atom in a molecule to which other atoms are bonded, serving as the reference point for measuring angles.
  • Lone Pair
    Non-bonding pair of electrons on the central atom that causes bond angles to decrease from their ideal values.
  • Ideal Bond Angle
    Optimal angle between atoms that minimizes repulsion, occurring when no lone pairs are present on the central atom.
  • Electron Group
    Region of electron density around a central atom, including both bonding pairs and lone pairs.
  • Repulsion
    Force between electron groups that pushes them apart, influencing the size of bond angles.
  • Bonding Group
    Set of electrons shared between the central atom and a surrounding atom, contributing to molecular structure.
  • Molecular Shape
    Three-dimensional arrangement of atoms in a molecule, determined by bond angles and electron groups.
  • Deviation
    Difference between the actual bond angle and the ideal value, typically caused by lone pairs.
  • 180 Degrees
    Ideal bond angle for a central atom with two electron groups and no lone pairs, resulting in a linear shape.
  • 120 Degrees
    Ideal bond angle for a central atom with three electron groups and no lone pairs, forming a trigonal planar shape.
  • 109.5 Degrees
    Ideal bond angle for a central atom with four electron groups and no lone pairs, characteristic of a tetrahedral shape.
  • Bonding Pair
    Pair of electrons shared between two atoms, forming a chemical bond and influencing bond angles.
  • Surrounding Atom
    Atom directly bonded to the central atom, helping define the bond angle in a molecule.
