What is the number of the lowest energy level that contains an f sublevel?
forsale [732]

Answer: n = 4.


Explanation:


1) The main energy level is represented by the principal (main) quantum number, n. It can be 1, 2, 3, 4, 5,6, or 7. It is the period number in the periodic table.


2) The next quantum number is the Azimuthal quantum number (ℓ), also known as angular quantum number. It indicates the subshell (sublevel) or type of orbital.


This quantun number may be:


s, p, d, or f.


3) For n = 1, there is only one ℓ number: 0; which is the orbital s


For n = 2, there are two possible ℓ numbers: 0 and 1; which are the orbitals s and p.


For n = 3, there are three possible ℓ numbers: 0, 1, and 2, which are the orbitals s, p, and d:


For n = 4, there are four possible ℓ numbers:0, 1, 2, and 3; which are the orbitals s, p, d, and f.


So, the f sublevel appears first time when n = 4, i.e the number of the lowest energy level that contains an f sublevel is 4.

A substance that produces hydroxide ions when placed in water is a(n) _____.
bekas [8.4K]

Answer: A substance that produces hydroxide ions when placed in water is base.

Explanation:

Bases are the substance:

  • Which gives negatively charged hydroxide(OH^-) ions in aqueous solution.
  • Which have pH value ranging from 7 to 14.
  • BOH(aq)\rightarrow B^+(aq)+OH^-(aq)

Where as acid gives positively charged hydronium ion(H^+) in aqueous solution.

Condensation is the change from liquid to water cycle
kogti [31]

Answer:

hi! merry xmas!

Explanation:

Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor.

Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.
