Shapes Chemical Bonding Flashcards
What is the octet rule?
Atoms tend to gain, lose, or share electrons in order to have a full outer shell of 8 electrons.
What is an ionic bond?
A bond formed by the transfer of electrons from one atom to another.
What is a covalent bond?
A bond formed by the sharing of electrons between atoms.
What is a polar covalent bond?
A covalent bond in which the electrons are shared unequally, leading to a partial positive and partial negative charge on the atoms involved.
What is a nonpolar covalent bond?
A covalent bond in which the electrons are shared equally, resulting in no partial charges on the atoms.
What is a metallic bond?
A bond formed by the sharing of electrons among a sea of delocalized electrons in a metal.
What is the VSEPR theory used for?
To predict the geometry of molecules based on the repulsion between electron pairs.
What is the molecular geometry of a molecule with 2 bonding pairs and 0 lone pairs?
Linear
What is the molecular geometry of a molecule with 3 bonding pairs and 0 lone pairs?
Trigonal planar
What is the molecular geometry of a molecule with 3 bonding pairs and 1 lone pair?
Trigonal pyramidal
What is the molecular geometry of a molecule with 4 bonding pairs and 0 lone pairs?
Tetrahedral
What is the molecular geometry of a molecule with 4 bonding pairs and 1 lone pair?
Trigonal bipyramidal
What is the molecular geometry of a molecule with 5 bonding pairs and 0 lone pairs?
Trigonal bipyramidal
What is the molecular geometry of a molecule with 6 bonding pairs and 0 lone pairs?
Octahedral
What is the shape of a molecule with the formula AX2E2?
Bent
