Explanation : Arsenic does not have any type of valence electron in the 3d orbital since it"s 3d orbital is completely filled.

You are watching: Arsenic does not have any valence electrons in the 3d orbital because

Arsenic has atomic number as 33 and the electron configuration is

*
3d^10 4s^2 4p^3" />. It plainly shows the the 3d orbit is totally filled i beg your pardon does no has an are to accommodate any electrons in the 3d orbital. Therefore, the electrons are accommodated in 4s and 4p orbitals,




Arsenic has a full of 5 valence electrons. These electrons fill the an initial orbital and also 3/4 of the 2nd orbital. The complete electron configuration of arsenic is 1s22s22p63s23p63d104s24p3.

Atomic number of Arsenic is 33. And also the digital configuration of Arsenic is  3d10 4s2 4p3. Now, valence electrons room the electrons current in outermost shell. With reference to Arsenic, valence covering is n = 4. And in 4th shell, there room no electrons present in d-orbital. On various other hand, third shell is not the valence covering in instance of Arsenic. Hence, electrons present of 3d covering of Arsenic cannot be referred together valence electrons. 


answer: the worth of enthalpy adjust will be -152.80 kj.

solution:

pressure = 1atm , temperature =

*
= 298 k
*

*

delta h_no=90.4kj/mol" />

*

*

*

*

given that pressure and temperature are same in both gases , the number of moles that both gases have the right to be identified by the right gas equation.

*

*

*

*

*

according to reaction 3 mole no room reacting v 1 mol of

*
,then 0.49 mol that no will certainly react through
*
mole of ozone that is 0.16 mole of ozone. Since, no is limiting reagent and
*
is an excessive reagent.

enthalpy change for the reaction between the offered volumes the the gases is :

*
