The electronic configuration of the element which is just above the element with atomic number 43 in the same group is ______.

1. 1s22s22p63s23p63d54s2

2. 1s22s22p63s23p63d54s34p6

3. 1s22s22p63s23p63d64s2

4. 1s22s22p63s23p63d74s2

Hint: Just substract 18 in atomic number 43 and find the next element which is just above the element with atomic number 43

The configuration of element which has 43 atomic number  is as follows

1s22s22p63s23p63d104s24p64d55s2

The next element which is just above the element with atomic number 43 has atomic number 25.

The electtronic configuration is as follows:

1s22s22p63s23p63d54s2

Hence option 1 is correct.
