All in the family
A pattern of regularly recurring properties.
What is periodicity?
The intermolecular attraction between a hydrogen atom an unshared pair of electrons on an electronegative atom of another molecule.
What is a hydrogen bond?
The energy required to cause a gaseous atom or ion to release an electron.
What is ionization energy?
The forces of attraction between the dipoles of polar covalent molecules.
What are dipole-dipole forces?
A chemical bond formed when electron pairs are unequally shared between two atoms.
What is a polar covalent bond?
A set of elements with similar properties.
What is a family?
The distance at which attraction is greatest and potential energy is least.
What is bond length?
A covalently bonded group of atoms with an overall positive or negative charge.
Forces of attraction between molecules.
What are intermolecular forces?
The general name for the attractive force that holds atoms together in compounds.
The vertical columns of the Periodic Table of elements.
What are groups?
Any bonding situation that cannot be properly represented by a single Lewis structure.
What is resonance?
All objects within a closed system tend to move toward a state of greater stability but lower potential energy.
What is the Second Law of Thermodynamics?
Intermolecular attractions resulting from electron motion and the creation of instantaneous, induced dipoles.
What are London dispersion Forces?
A chemical bond formed when electron pairs are equally shared between two atoms.
What is a nonpolar covalent bond?
The horizontal rows of the Periodic Table of Elements.
What are periods?
A large crystal formed by a network covalent structure.
What is a macromolecule?
The amount of energy involved when an electron is acquired by a neutral gaseous atom.
What is electron affinity?
The measure of the power of an atom in a molecule to attract electrons to itself.
What is Electronegativity?
A chemical bond formed by the attraction of cations for anions.
What is an ionic bond?
Elements with both metal and nonmetal properties.
The combining of atomic orbitals of similar energies on the same atom to provide special orbitals of equal energy for the purpose of bonding.
What is hybridization?
The measure of the power of an atom in a molecule to attract electrons to itself.
What is electronegativity?
The energy required to cause a gaseous atom or ion to release an electron.
What is ionization energy?
A chemical bond formed by the attraction between positive metal ions and surrounding mobile electrons.
