A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...
Chemical bonding refers to the attraction between atoms and can come in several different types with varying strength. It allows the formation of substances with more than one atomic component and ...
Ken Wade recalls his own undistinguished part in the space race, and notes how carboranes revitalized boron hydride chemistry and modified our ideas of chemical bonding.
Students look more deeply into the structure of the atom and play a game to better understand the relationship between protons, neutrons, electrons, and energy levels in atoms and their location in ...
Metallic lattices do not contain fixed numbers of atoms. This means that the chemical formula used for a metal is simply the symbol for the element. For example, the formula for iron is Fe, even ...
Energy is required to break a covalent bond between two atoms to overcome the attractive force. Bond breaking is an endothermic process. The opposite is true if we want to make new bonds.
