Compounds usually have the same properties as the bonds they are made from true or false
gavmur [86]
Well , I will say this is a false statement.
This is because compounds which were all made by the same bond have same physical properties but different chemical properties.

Chemical Properties :
How do the subtances react with ( water, acid,alkaline, base , gas like oxygen, etc. )

Physical Properties :
- Solubility of those subtances in (water or organic solvent )
- Electric Conductivity
- Melting or Boiling Point
- Density
- Smell (exp : Ammonia has pungent smell , Esters has fruity smell)

Two electrons are found in the same atom. One has the quantum number set (3, 2, 0, +?), and the other has the quantum number set
Vilka [71]

D. Same energy level but different sublevel.

<h3>Explanation</h3>

There are four quantum numbers [1]:

  • <em>n</em><em>, </em>the principal quantum number,
  • <em>l</em>, the orbital angular momentum quantum number,
  • <em>m_l</em>, the magnetic quantum number, and
  • <em>m_s</em>, the electron spin quantum number.

As their names might suggest:

  • <em>n </em>determines the main energy level of an electron.
  • <em>l</em> determines the type of sublevel of an electron.
  • Each sublevel might contain more than one orbital. <em>m_l</em> gives the orbital of an electron.
  • Each orbital contains up to two electrons. <em>m_s</em> tells two electrons in the same orbital apart.<em> </em>

The two electrons in question come from the same atom. The question suggests that they have the same <em>n</em>, <em>m_l</em>, and <em>m_s</em>. As a result, both electrons are in main energy level <em>n</em> = 3. They share the same spin.

However, the two electrons differ in their value of <em>l</em>.

  • <em>l </em>= 2 for the first electron. It belongs to a <em>d</em> sublevel.
  • <em>l </em>= 1 for the second electron. It belongs to a <em>p</em> sublevel.
