Answer: Noble gas configuration is the ionisation of valence electrons using the octet rules.
Explanation:
Noble gases are the halogen, iodine etc. they form molecules using anion valence electrons in order build octet structures.
The sublevel designation=6f
The allowed values of the magnetic quantum number are: ml=−3,−2,−1,0,+1,+2,+3
The number of orbitals=7
How are these calculated?
- We are given values for the principal and orbital angular momentum quantum numbers: n=6 ,l=3
- The value of n tells us the shell number. The value of l tells us the type of atomic orbital, which here is an "f" orbital. Therefore, the subshell (sublevel) designation is:6f
- For this subshell the allowed values of the magnetic quantum number are: ml=−3,−2,−1,0,+1,+2,+3
- Each value of ml represents one orbital that holds two electrons. Therefore, we can conclude that there are seven orbitals present at the "6f" subshell, so it has a degeneracy of seven.
What are quantum numbers?
- Quantum numbers are used to describe where around a nucleus a particular electron can be found.
- In any given atom, each electron can be described by four quantum numbers.
- These are n,l,m1,ms
- The values that each number can be are based on a set of rules.

Answer:
Acid salts are the converse of basic salts; they are formed in the neutralization reaction between a strong acid and a weak base. ... For instance, in the reaction of hydrochloric acid (a strong acid) with ammonia (a weak base), water is formed, along with ammonium chloride.
Explanation:
Nitrous acid is prepared in situ from hydrochloric acid and sodium nitrate because it is a weak acid and unstable. It only exists in an aqueous solution.
Nitrous acid is an unstable acid which gets decompose into the water , nitrogen dioxide and nitrogen monoxide gas.
Whereas nitric acid is highly stable acid which can be easily prepared from its reagent and it can easily be stored for future use.
