Term
Chemical Bond
Definition
The attraction the results from the redistribution of electrons between two or more atoms, leading to a more stable configuration-- particularly by filling the outer electron shells-- and the holds the two atoms together. The principal kinds of chemical bonds are ionic, covalent and metallic.
Term
Ionic Bond
Definition
A chemical bond in which the electrostatic force between two oppositely charged ions holds the atoms in place, often formed as onr atom gives up an electron while another recieves it, lowering chemical potential energy when atom shells are filled.
Term
Metal
Definition
An element or combination of elements in which the sharing of a few electrons amoun all atoms results in more stable electron arrangement; characterized by a shiny luster and ability to conduct electricity
Term
Covalent Bond
Definition
A chemical bond in which reignboring molecules share electrons in a strongly bonded group of at least teo atoms.
