Because magnesium loses its electrons easily than aluminum
Boron's atomic number is 5
Answer:
There is an overall release of energy when bonds form.
Explanation:
There is a general release of energy when bonds form. This energy is called bond energy.
Bond energy is involved in the breakdown or formation of one or more bonds between atoms of a molecule. Atoms bond with each other to achieve their electronic stability, that is, they move from a higher energy situation to a lower energy one. With this we can state that when the bond between atoms is formed, energy is released; therefore, its breakdown depends on energy absorption.
Ethanol is a polar molecule containing hydrogen bonds at the OH groups. These bonds are much stronger and therefore take much more energy to break, hence the higher melting and boiling points
Ethane on the other hand is non-polar as it is a hydrocarbon and only contains London Dispersion forces between molecules, which are the weakest of the intermolecular forces, meaning it is easy to break them.
