Melting point
The temperature at which the solid and liquid phases of a substance coexist in equilibrium.Metal
Metal
One of a class of elements located on the left side of the periodic table, possessing low ionization
energies and electronegativities. Metals readily give up electrons to form cations; they possess
relatively high electrical conductivity and are lustrous and malleable.
Metallic bonding
Metallic bonding
The type of bonding in which the valence electrons of metal atoms are delocalized throughout
the metallic lattice.
Metalloid
Metalloid
An element possessing properties intermediate between those of a metal and those of a
nonmetal. Also called a semimetal.
Micelles
Micelles
Clusters of molecules possessing hydrophilic ionic heads facing the surface of a sphere where
they can interact with water, and possessing hydrophobic hydrocarbon tails in the interior. Soaps
form micelles, facilitating the dissolution of oils and fats.
Miscible
Miscible
Able to mix in any proportion.
