`1s^2 2s^2 2p^6 3s^1` shows configuration of

Consider the ground state electronic configurations given below and answer the following. A : 1s^2 2s^2 2p^5 , B : 1s^2 2s^2 2p^4 , C : 1s^2 2s^1 , D : 1s^2 2s^2 2p^6 3s^1 , E : 1s^2 2s^2 2p^6 Arrange these configurations in order of increasing I.E.

An element A has the configuration 1s^(2)2s^(2)//2p^(6)3s^(1) and the elemen B has the configuration 1s^(2)2s^(2)2p^(4) Give the formula of the compound formed. 1s^(2)2s^(2)2p^(6)3s^(1) while the configuration of B is 1s^(2)2s^(2)2p^(5). What type of bond is likely to be formed between them ?

The configuration is 1s^(2) 2s^(2) 2p^(5) 3s^(1) shows :

The configureation is 1s^(2) 2s^(2) 2p^(5) , 3s^(1) shows :

1s^(2)2s^(2)2p^(6)3s^(2) is the electronic configuration of the metal

The electronic configuration of the elements are given below. A- 1s^2 2s^2 2p^6 3s^2 3p^4 B- 1s^2 2s^2 2p^6 3s^2 C- 1s^2 2s^2 2p^6 3s^2 3p^5 D- 1s^2 2s^2 2p^6 3s^1 Which of these elements show +2 oxida-tion state?

The elecronic configuration 1s^2 ,1s^2 2p^6, 3s^1 3p^1 correctly describes :

Pick out the wrong subshell electronic configuration from those given below? a) 1s^2 2s^2 2p^7 b) 1s^2 2s^2 2p^2 c) 1s^2 2s^2 2p^6 3s^1 d) 1s^2 2s^2 2p^6 3s^2 3p^6 3d^2 4s^1 e) 1s^2 2s^2 2p^6 3p^6 3d^2 4s^2
