N, our atmosphere is about 80% nitrogen(N) and about 20% oxygen(O)
Answer: Option (d) is the correct answer.
Explanation:
An orbital is defined as the energy shell which can contain a maximum of two electrons with opposite spins.
A wave like behavior of an electron is determined by an orbital and basically an orbital acts like a mathematical function.
For example, in a p-sub shell the orbitals present are
,
and
.
Therefore, we can conclude that orbitals are defined by energy level.

Answer:
ester
Explanation:
Carboxylic acids and alcohols react in the presence of strong acid to produce an ester and water. The two carbon chains come together, which is the condensation, and then water is generated, which is dehydration. The resulting compound is an ester.
Answer:
Element in the same group have similar chemical properties.
