Answer:
Transverse waves particles move horizontal to the way the waves move.Longitudinal wave particles move parallel to where the wave is going. Surface wave particles move in a motion like a circle.
Answer:
A region of high electron density between two positively charged nuclei, such that a net attractive force results.
Explanation:
Typically, the covalent bond is rationalized on the basis of the sharing of 2 electrons between two atomic nuclei. The modern covalent bond is considered to be a region of high electron density between 2 positively charged atomic nuclei, such that internuclear repulsion is minimized, and a net attractive force results.
Ionic bonds fall outside this umbrella.
