Question

1.- The orbital diagram for a ground state oxygeen atom is:???? 2.-Which ground state atom has an electron configurationdescribeed by the following orbital diagram? a)phosphorus    b)nitrogen   c)arsenic       d)vanadium     e)sulfur a)Sn    b)Sb    c)Pb    d)Bi     e)Te 1.- The orbital diagram for a ground state oxygeen atom is:???? 2.-Which ground state atom has an electron configurationdescribeed by the following orbital diagram? a)phosphorus b)nitrogen c)arsenic d)vanadium e)sulfur 3.-Which element has the ground-state electronconfiguration? a)Sn b)Sb c)Pb d)Bi e)Te

Explanation / Answer

1) [He]    ||       ||     |    |              2s                  2p 2) Phosphorous. P has 2 3s electrons and 3 3p electrons 3) That is Tellurium It is on the fifth row. It fills up with 2 5s electrons. Then yougo across the transition metals and fill up the 4d with 10. Thenfill up with 4 5p. From wikipedia, electron config of Tellurium [Kr]5s2 4d10 5p4
