What does the group number on the periodic table tell you about the electron configuration of a
jarptica [38.1K]

Answer:

The group number in the periodic table represents number of valence electrons of the elements in a certain group.

Explanation:

There are s, p, d, and f blocks, which you can see in periodic table

The s-block and p-block together are usually considered main-group elements, the d-block corresponds to the transition metals, and the f-block encompasses nearly all of the lanthanides (like lanthanum) and the actinides (like actinium)

There are three main principles, which may useful for you:

  • The Pauli exclusion rule basically says that at most, 2 electrons are allowed to be in the same orbital.
  • Hund’s rule explains that each orbital in the subshell must be occupied with one single electron first before two electrons can be in the same orbital.
  • The Aufbau process describes the process of adding electron configuration to each individualized element in the periodic table.

Hope this helps!

According to reference table adv-10, which is the strongest reducing agent?
Mumz [18]
Li(s)    (answer  A)   
    Li  is  strongest  reducing  agent  because  of  the   lowest  standard reduction  potential.  when  something  is  oxidized, it  reduces  another  substance,  becoming a  reducing.Hence  Lithium  is  strongest  reducing  agent. Reducing  agent   is  stronger  when  it  has  a  more  positive  oxidation potential.

According to the below equation, how many moles of SO2 are required to generate 1.43×1024 water molecules?
podryga [215]
Make sure the equation is always balanced first. (It is balanced for this question already) 6.022 x 10^23 is Avogadro’s number. In one mole of anything there is always 6.022 x 10^23 molecules, formula units, atoms. For one mol of an element/ compound use molar mass (grams).

Multiply everything on the top = 8.61x10^47
Multiple everything on bottom= 1.20x10^24
Divide top and bottom = 7.15x10^23

Answer: 7.15x10^23 mol SO2
