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.

Answer:
Explanation:
The average atomic mass (sometimes called atomic weight) of an element is the weighted average mass of the atoms in a naturally occurring sample of the element. Average masses are generally expressed in unified atomic mass units (u), where 1 u is equal to exactly one-twelfth the mass of a neutral atom of carbon-12.
The answer is:
C) Sound is a mechanical wave and needs a medium to travel through while light is an electromagnetic wave.
