Q. How does the metallic character of the elements of group I changes as we if we move downwards.
Q. What is the reason that carbon atom forms only covalent compounds?
Q. Discuss the variance of valency and metallic character of elements when moving from left to right in a period?
Q. What do you mean by the functional group present in an organic compound. Write the formula of the functional group present the following compounds:
Answers
Explanation:
1..increase downward
2..because it need four electron for full fill thier valency
1. Metallic character is essentially how easy an atom gives away an electron to become a cation ( which metals do) . Going down a group, the atomic radius increase as well.
Therefore, going down a group, since less energy is required to remove an electron, it becomes “easier”, and metallic character increase.
2. Moving from left to right in a period, metallic character decreases and non-metallic character increases. ... In a group, metallic character increases from top to bottom and non-metallic character decreases. This is because atomic size increases and so the valence electrons can be easily removed.
3. In organic chemistry, a functional group is a specific group of atoms or bonds within a compound that is responsible for the characteristic chemical reactions of that compound. The same functional group will behave in a similar fashion, by undergoing similar reactions, regardless of the compound of which it is a part.
