Covalent Bonding (H)

Across
a molecular orbital that can be occupied by two electrons of a covalent bond
a molecule that has two poles, or regions with opposite charges
a chemical formula that shows the arrangement of atoms in a molecule or a polyatomic ion; each dash between a pair of atoms indicates a pair of shared electrons
a covalent bond in which the electrons are shared equally by the two atoms
one of the two or more equally valid electron dot structures of a molecule or polyatomic ion
an orbital that applies to the entire molecule
intermolecular forces resulting from the attraction of oppositely charged regions of polar molecules
a _______ covalent bond is formed when one atom contributes both bonding electrons
the mixing of several atomic orbitals to form the same total number of equivalent hybrid orbitals
a molecule consisting of two atoms (ex. H2, O2, N2)
a molecular shape that results when there are two bonds and two lone pairs around the central atom in the molecule.
attractive forces in which a hydrogen covalently bonded to a very electronegative atom is also weakly bonded to an unshared electron pair of another electronegative atom
a _____ bond is formed when two atoms share a pair of electrons
a molecular shape that results when there are three bonds and two lone pairs around the central atom in the molecule.
a bond formed when two atomic orbitals combine to form a molecular orbital that is symmetrical around the axis connecting the two atomic nuclei
Down
a compound that is composed of molecules
a(n) _____ pair of valence electrons are the electrons that are not shared between atoms
a ______ bond is formed by the sharing of electrons between atoms
a molecular shape that results when there are four bonds and no lone pairs around the central atom in the molecule
a _______ covalent bond is a bond between atoms in which the electrons are shared unequally
the energy required to break the bond between two covalently bonded atoms; this value is usually expressed in kJ per mol of substance
the two weakest intermolecular attractions—dispersion interactions and dipole forces
a molecular shape that results when there are four bonds and no lone pairs around the central atom in the molecule.
a _____ molecule is molecule in which one side of the molecule is slightly negative and the opposite side is slightly positive
a _____ bond is formed when two atoms share two pairs of electrons
a solid in which all of the atoms are covalently bonded to each other
a ______ covalent bond is formed when three pairs of electrons are shared by two atoms
a covalent bond in which the bonding electrons are most likely to be found in sausage-shaped regions above and below the bond axis of the bonded atoms
