In long form of periodic table, an element has electronicconfiguration 1s^(2)2s^(2)2p^(6)3s^(2)3p^(3). Thus what will be the atomic number of element which is just below this element in its group ?

In long form of periodic table, an element has electronicconfiguration

1.	In long form of periodic table, an element has electronicconfiguration 1s^(2)2s^(2)2p^(6)3s^(2)3p^(3). Thus what will be the atomic number of element which is just below this element in its group ?
Answer» <P>23 16 33 47 Solution :Electronic CONFIGURATION is given as : `1S^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(3)` ` :. ` TOTAL electrons = 15 ` :. ` Element is P of group 15 or VB The element just below to P is As As has ATOMIC number = 33 and As is of group 15 or VB
