The question is incomplete, here is the complete question:

Give the charge and full ground-state electron configuration of the monatomic ion most likely to be formed by each element: (a) P, (b)  Mg,  (c) Se

<u>Answer:</u>

<u>For a:</u> The electronic configuration of the monoatomic ion formed is 1s^22s^22p^63s^23p^6

<u>For b:</u> The electronic configuration of the monoatomic ion formed is 1s^22s^22p^6

<u>For c:</u> The electronic configuration of the monoatomic ion formed is 1s^22s^22p^63s^23p^64s^23d^{10}4p^6

<u>Explanation:</u>

An ion is formed when a neutral atom looses or gains electrons.

  • When an atom looses electrons, it results in the formation of positive ion known as cation.
  • When an atom gains electrons, it results in the formation of negative ion known as anion.

For the given elements:

(a) Phosphorus

This is the 15th element of the periodic table having electronic configuration of 1s^22s^22p^63s^23p^3

This element will gain 3 electrons to form P^{3-} ion

The electronic configuration of the monoatomic ion formed is 1s^22s^22p^63s^23p^6

(b) Magnesium

This is the 12th element of the periodic table having electronic configuration of 1s^22s^22p^63s^2

This element will loose 2 electrons to form Mg^{2+} ion

The electronic configuration of the monoatomic ion formed is 1s^22s^22p^6

(c) Selenium

This is the 34th element of the periodic table having electronic configuration of 1s^22s^22p^63s^23p^64s^23d^{10}4p^4

This element will gain 2 electrons to form Se^{2-} ion

The electronic configuration of the monoatomic ion formed is 1s^22s^22p^63s^23p^64s^23d^{10}4p^6

The density of gas particles in a section of Earth’s atmosphere decreases. Which of the following is the most likely explanation
Bad White [126]
<span>This is due to the fact that the air pressure in that certain section of Earth’s atmosphere decreased. As density of gas particles decreases as air pressure decreases. Therefore, density of gas particles and air pressure have a direct relationship. An increase in air pressure would then effect to an increase in gas particles. </span>

Which of the following statements is true? A) This reaction will be spontaneous only at high temperatures. B) This reaction will
viktelen [127]

Answer:

D) This reaction will be nonspontaneous only at high temperatures.

Explanation:

According the equation of Gibb's free energy -

∆G = ∆H -T∆S

∆G = is the change in gibb's free energy

∆H = is the change in enthalpy

T = temperature

∆S = is the change in entropy .

And , the sign of the  ΔG , determines whether the reaction is Spontaneous or non Spontaneous or at equilibrium ,

i.e. ,

if

  • ΔG < 0 , the reaction is Spontaneous
  • ΔG > 0 , the reaction is non Spontaneous
  • ΔG = 0 , the reaction is at equilibrium

The reaction has the value for ∆H = negative , and ∆S = negative ,

Now ,

∆G = ∆H -T∆S

     = ( - ∆H ) - T( - ∆S )

     =  ( - ∆H ) +T(  ∆S )

Now, for making the reaction Spontaneous ΔG = negative ,

Hence ,

The temperature is low, then the value for  ΔG will be negative , i.e. , Spontaneous reaction .

And , vice versa , at higher temperature , the reaction will have ΔG positive , and the reaction will be non -Spontaneous reaction .

The standard free energy of formation will be zero , only for the compounds that are in their pure form ,

Hence , Al(s) will have ΔG = 0 .
