Properties of Compounds
What is melting point?
A type of bond formed be the transfer of one or more electrons.
What is an ionic bond?
A type of bond formed when two atoms share their valence electrons.
What is a covalent bond?
The type of bond that forms when electronegativity difference is less than 1.7.
What is a covalent bond?
The chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons, or attraction between positive ions and surrounding mobile electrons?
What is metallic bond?
The temperature at which a liquid boils and turns to vapor.
What is boiling point?
This type of atom is a positive ion because it loses one or more electrons.
What is a cation?
A neutral group of atoms that are held together by covalent bonds.
What is a molecule?
The type of bond that forms when electronegativity difference is greater than 1.7.
What is an ionic bond?
This salt (an ionic compound made of metal and nonmetal ions), forms from solar evaporation of water from brine. It can be used to make batteries.
What is lithium salt?
The degree of compactness of a substance.
What is density?
This type of atom is a negative ion because it gains electrons.
What is an anion?
A chemical compound in which the simplest units are molecules.
What is a molecular compound?
On the spectrum of electronegativity difference, this type of covalent bond forms between 0.3 and 1.7.
What is a polar-covalent bond?
The three-dimensional structure of a molecule resulting from the electron pairs arranging themselves as far apart as possible.
What is valence-shell electron-pair repulsion, or VSEPR?
The degree to which a specified material conducts electricity,
What is electrical conductivity?
This structure is formed by atoms in a solid ionic compound.
What is a crystal?
The melting and boiling points of molecular compounds are much (lower or higher) than those of ionic compounds.
What is lower?
On the spectrum of electronegativity difference, this type of covalent bond forms at less than 0.3.
What is nonpolar-covalent bond?
Using the Lewis Dot Structure, draw the covalent bond for aluminum (AL) and oxygen (O).
What is Al2O3?
This element has the highest melting point: citric acid, paraffin wax, or table salt.
What is table salt?
The chemical formula for calcium flouride?
What is CaF2?
The chemical formula for aluminum (AL) and oxygen (O).
What is Al2O3?
A greater difference in electronegativity corresponds to a (more or less) complete transfer of electrons from one atom to the other.
What is a more complete transfer of electrons?
This pair of electrons forms a bond with the least ionic character.
a. K and Cl
b. O and Cl
c. Na and Cl
What is O and Cl?
