Enter your answer in the provided box. How many unpaired electrons are present in the ground state of the atoms in Group 6A(16)

Chemistry
1 answer:
Nat2105 [25]3 years ago
6 0

Answer:

Two unpaired electrons

Explanation:

The elements of group 16 include; oxygen, sulphur, selenium, tellurium etc. These elements contain six electrons on their outermost shells. These six electrons are comprised of two lone pairs and two unpaired electrons. The outermost electron configuration of group 16 elements is ns2np4.

Let us take a well known example, look at the formation of water. Oxygen contains two lone pairs of electrons and two unpaired electrons which are used to bond to two hydrogen atoms to form H2O. Similar hydrides are formed with other group 16 elements.

What makes the smell in chlorine?
padilas [110]

Pool smell is due, not to chlorine, but to chloramines, chemical compounds that build up in pool water when it is improperly treated. Chloramines result from the combination of two ingredients: (a) chlorine disinfectants and (b) perspiration, oils and urine that enter pools on the bodies of swimmers.

  • The change in color from blue to pink of the cobalt complexes here has been the basis of cobalt chloride indicator papers for the detection of the presence of water. It is also used in self-indicating silica gel desiccant granules.
  • Pink cobalt species + chloride ions ⇌ Blue cobalt species + water molecules

<u>Explanation</u>:

  • The adjustment in color from blue to the pink of the cobalt complexes here has been the premise of cobalt chloride indicator papers for the detection of the presence of water. It is likewise utilized in self-demonstrating silica gel desiccant granules.  

Pink cobalt species + chloride particles ⇌ Blue cobalt species + water molecules  

  • The response of [Co(H2O)6]2+(aq) + 4Cl–(aq) → [CoCl4]2–(aq) + 6H2O(l) is endothermic. In this manner, as per Le Chatelier's rule, when the temperature is raised, the situation of the balance will move to one side, shaping a greater amount of the blue complex particle at the expense of the pink species.  
  • Including concentrated hydrochloric raises the chloride particle fixation, making the equilibrium move to one side, as per Le Chatelier. Including water brings down the chloride particle fixation, moving the equilibrium the other way.
  • As an extension, it is conceivable to show that it is the Cl–particles in the hydrochloric acid that move the balance by including a spatula of sodium chloride rather than the pink arrangement. This delivers a bluer color, however, this may take some time because the salt is delayed to dissolve.
