Chapter 4: Molecular Compunds
the bond formed when 2 atoms share electrons
a group of atoms held together by covalent bonds
the optimum distance between nuclei in a covalent bond
a compound that consists of molecules rather than ions
molecular compounds have high melting points
molecular compounds are soluble in water
molecular compounds are composed entirely of non-metals
molecular compounds' smallest components are molecules
carbon nitrogen and oxygen are the elements most often present in...
molecules are composed of oppositely charged ions
molecules are composed of electrically _____ atoms sharing electrons
what has high melting and boiling points due to strong attractive forces in oppositely charged ions?
weaker forces between molecules are called...
a formula that shows the number and kinds of atoms in 1 molecule of a compound
a molecular representation that shows the connections among the atoms y using lines to represent covalent bonds
a molecular representation that shows both the connections among atoms and the locations of lone pair electrons
a pair of electrons that is not used for bonding
in _____ compounds, the smallest particle is an ion. in _______ compounds the smallest particle is a molecule
a molecular representation in which the bonds are not specifically shown but rather understood by the order in which the atoms are written
A molecular formula gives the number of atoms that are combined in one molecule
(The formula “Cl2” says the chlorine molecule is made of two atoms bonded together)
