Explanation:
Electronegativity determines the polarity . There may be two atoms in a bond with high electronegativity, in such cases the positive charge is given to atom with comparatively lower electronegativity. Electronegativity determines the easiness with which an atom attract electrons in a chemical bond. A polar bond is formed when the difference in the electronegativity of two combining atoms is between 0.4 and 1.7. The correct direction is
1. C+ ---- O-
2. O+ ---- Cl-
3. O+ ----- F-
4. C+ ----- N-
5. Cl- ----- C+
6. S- ----- H+
7. S+ ----- Cl -

Explanation:
The absence of an unbalanced force, an object at rest will stay at rest and an object in motion will stay in motion.
<span>A bright-line spectrum of sodium
is produced when energy is absorbed as electrons move from higher to lower
electron shells. Electrical energy tends to excite electrons causing them to
have this reaction. When an electron is excited with electricity the electrons
tend to move up a shell. Moving up a shell makes the electrons unstable. Eventually,
these unstable electrons will come back down a shell and what will be left are
emissions of photons. These photons form different wavelengths resulting to a
bright-line spectrum.</span>
