How are covalent bonds different from ionic bonds?

In ionic bonding, atoms transfer electrons to each other. In contrast, atoms with the same electron negatively share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
