Unit 1 - Chapter 2: Chemical Bonding Flashcards
What rule of thumb allows you to predict the way in which bonds form between atoms?
octet rule
What is it call when bonds form between atoms, the atoms, gain, lose, or share electrons in such a way that they create a filled outer shell containing 8 electrons?
octet rule
What do you call the attractive electrostatic force between a negative ion and a positive ion?
ionic bond
What do you call a chemical compound composed of ions that are held together by ionic bonds?
ionic compound
What do you call the attraction between atoms that result from the sharing of electrons?
covalent bond
What do you call a chemical compound that is held together by covalent bonds?
molecular compound
What do you call a covalent bond that results from atoms sharing one pair of electrons?
single bond
What do you call a covalent bond that results from atoms sharing two pairs of electrons?
double bond
What do you call a covalent bond that results from atoms sharing three pairs of electrons?
triple bond
What do you call a pair of electrons that is shared by two atoms, thus forming a covalent bond?
bonding pair
What do you call a pair of electrons that is not part of a covalent bond?
lone pair
What do you call a Lewis diagram that portrays a complete molecular compound?
lewis structure
What do you call a molecular compound that has an excess or a deficit of electrons, and thus has a change?
polyatomic ion
What is the octet rule?
when bonds form between atoms, the atoms, gain, lose, or share electrons in such a way that they create a filled outer shell containing 8 electrons.
What do you call a covalent bond around which there is an uneven distribution of electrons, making one end slightly positively charged and the other end slightly negatively charged?
polar covalent bond
What do you call the difference between the electronegativities of two atoms?
electronegativity difference
What do you call a base that is soluble in water?
alkali
What do you call an acid composed of hydrogen, oxygen, and atoms of at least one other element?
oxoacid
What do you call a diagram that has the chemical symbols connected by lines to show the connections among atoms in a chemical compound?
structural formula
What do you call the temperature at which a compound changes from solid to a liquid?
melting point
What do you call the temperature at which a compound changes from a liquid to a gas?
boiling point
What do you call a molecule with slightly positively charged end (positive pole) and a slightly negatively charged end (negative pole)?
dipole
What do you call the attractive force between the positive end of one molecule and the negative end of another molecule?
dipole-dipole force
What do you call attractive forces that act between molecules?
intermolecular forces
What do you call the ability of a substance or an object to allow an electric current to exist within it?
electrical conductivity
