Question

the required information. (12 marks) An excited state of this element has the electron configuration [Kr An element with the electron jssid'5p ground state electron configuration contains unpaired electrons in 7s c. An element with the ground state electron configuration is [Nel 33p 3p d. e. the maximum number of electrons with n ; L, m f. the maximum number of electrons with n-4 An element with the 4 Quantum Numbers are: n-4; L-1; mL : 0; m,-- the maximum number of electrons with n-4; L 0 j the number of orbitals with n- 4 k. the number of different types of orbitals n 3; L-2 the number of orbitals with n-4,L= 1 Predict all possible valencies ofelement #15. These valences could Using Quantum Theory explain why this element has these valences and which would be the most stable. Show all works (including orbital box diagram) (6 marks) not be explained by Bohr's theory

Answer 1

a)Ans_Grounstate Electronic configuration ofANTIMONY(Sb)is_(Kr)4d¹⁰5s²5p³

But excitedstate electroniconfiguratios is_(kr)4d¹⁰5s¹5p³6d¹

^{b)Ans_In7s orbital unpaired electron=1 Reason is any S_orbital maximum fiils with2electrons}

C)Ans_This is phosphrous electronic configuration

d)The given quantumnuberdata equal to 4P_orbital

e)The given quantum number =1S orbital_total number electrons inthis orbital=2

f)If pricipal quantum number(n)known then total no electrons=2n²

If n=4 then2(4)²=32

I)Thegiven data =4SOrbital,max nuber of electrons equal toTwo

J)If n is given then total no of orbital equalto n²

^{n=4 Total no of orbitals =16}

^{k)3dxy,3dyz,3dzx,3dx2y2,3dz2}

^{i)3(4p) 4px,4py,4pz}
