Explanation:
Chemical bonding results from attractive forces that joins chemical species.
- Noble gases show no tendency to combine with themselves or with other kinds of atoms because of their completely filled outer energy levels.
- The driving force for most interatomic bonding is the tendency to have completely filled outer energy levels just like the inert gases.
- The stable configuration can be attained by losing or gaining of electrons or sharing of pairs of electrons.
Two examples of how bonds form:
Bonds can be formed by:
- Losing and gaining of electrons to form electrovalent or ionic bonds.
- Sharing of electrons to form covalent bonds.

Answer:
it means the velocity is changing.
the rate of change of velocity is acceleration
so it means the body is accelerated at 2m/s^2
The density of air reduces as humidity and amount of water in the air increases. <span> The speed of sound is inversely proportional to the root of density, therefore sound travels faster on a cloudy day than on a dry day so, velocity of sound increase.</span>
