Answer: An atom has either tendency of accepting or losing electron, on the basis of this virtue it is named as
- Electronegative: An atom has tendency to attract the shared pair of electron towards itself is called electronegative.
- Electropositive: An atom that has tendency to give the shared pair of electron towards an electronegative atom is called electropositive.
For the existence of dipole within a molecule there must be a difference in electronegativity of the atoms participating in it. All the molecules here have dipole moment because the atoms participating in them have a difference in electronegative.
Answer:
See below.
Explanation:
A lot of heat is produced in this reaction so much that the sodium catches fire. If there is a lot of water and just a small piece of sodium it will not catch fire. Potassium reacts more vigorously than sodium and will always catch fire.
