Which electron configurations of neutral atoms represent excited states? D (Xe]6s24h [Kr]5s4d [Ar]4s23d3 1s22s22p3s23p63d2 252 Which neutral atoms have the given electron configurations in either a ground state or excited state? Enter the name or symbol. [Ar]4s23dº: [Xe]6s24h:

Answer 1

Excited state electronic confignation is the electronic Configuration in which electron jumps from a love energy subshell to a higher energy subashellson we can say that electron & bresent in a higher energy subshell instead of low energy subshell. () Note!- If all the rules that is Aufbau, Pauli and exclusion prunciple, Hund's rule of maximum multiplicity are followed in the ginen electusnie Configuration then it is said to be ground state electronic configuration of the given element. Ty thes sunkes are not followed then the given electronic configuration is said to be excited state etsconic confignation. The subshell having lower value of (ntl) is lower in ki energy and the subshell having higher value of (nth) is higher in energy. If (ntl) value is same then the lower the value of n energy will be lower of that subshell and the subshell having higher value of n will have more higher every nvalues no pecinciple queuntun number Subshell Os as a b (35 36 30 1-0 for s subhell nal 1 2 3 93 4 5 1=1 p 1-2 d Energy order of subhell tis La S220 235 236 LYS odkup 1=3 ff & subshell no. of total number of elections can be occupied. 14

1 Xe 65² uf' r does not represent excited state because the loweer energy subsney & 657 is Debita fully filled and they no electron is to transfered from low energy subshell to higher enerzy subshell. 2) Iun 5s4d5 It is a Ground state electronic Configuration of Mo & Molybdenum] Through here election is transferred from tower present in higher energy subshell hud? instead of 1553 . But this is an exception. So it is not exŭted state . This is also a Grond state electronic Configuration of Vanadium & vf tower the of 1553 . sed state agy subshuttons . But 3) [Ar] 45² 3d is not (4) 15225²268332 3p 3d². This is the Excuted state electronie configuration because in this elections are present in 3d subshell instead of being in the lower energy subshell us? We can write it abo like 31522522635²38452d- 5) 25 represents Ground state electronic configuration Answer - 1822322 8 332 33 3d electronic Configuration represents excited state,
