3.1-3.4 Chemical Compounds Flashcards
the combining of atoms to form molecules or compounds
Chemical Bond
electrons in the outermost energy level of an atom
valence electrons
an attraction between oppositely charged ions
ionic bond
a compound made of oppositely charged ions
ionic compound
sodium chloride; an ionic compound
table salt
The arrangement of ions in a repeating three-dimensional pattern
crystal lattice
a chemical compound formed by the sharing of electrons
covalent compound
a weaker attractive force than an ionic bond
covalent bond
the smallest particle into which a covalently bonded compound can be divided and still be the same compound.
molecule
any compound that increases the number of hydronium ions when dissolved in water.
acid
destroys body tissue, clothing, and many other things
corrosive
a compound that can reversibly change color depending on conditions such as pH
indicator
an indicator
bromthymol blue
any compound that increases the number of hydroxide ions when dissolved in water
base
when all the molecules of an acid break apart
strong acid
