33, because p block has 6 elements per period.
Max unpaired is halfway, so 3rd.
3rd element of 4th period p-block is 33.

**Explanation:**
The maximum number of unpaired 4p electrons can be found by determining the electron configuration of elements in the 4p block of the periodic table.
The electron configuration of elements in the 4p block follow the pattern: 4s^2 4p^1, 4s^2 4p^2, 4s^2 4p^3, 4s^2 4p^4, 4s^2 4p^5, 4s^2 4p^6.
Let's go through the options to determine the element with the maximum number of unpaired 4p electrons:
a) Atomic number 33: The electron configuration of the element with atomic number 33 is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^3. In this configuration, there are three unpaired electrons in the 4p orbital.
b) Atomic number 26: The electron configuration of the element with atomic number 26 is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^6. In this configuration, there are no unpaired electrons in the 4p orbital.
c) Atomic number 23: The electron configuration of the element with atomic number 23 is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^3. In this configuration, there are no unpaired electrons in the 4p orbital.
d) Atomic number 15: The electron configuration of the element with atomic number 15 is 1s^2 2s^2 2p^6 3s^2 3p^3. In this configuration, there are three unpaired electrons in the 4p orbital.
Therefore, the element with the maximum number of unpaired 4p electrons is the element with atomic number 33, which corresponds to option A.

It's a easy question ...by direct filling electrons according to afbau principal will gives us answer.. for option a...33 electron 1s----2electron, 2s----2 electron, 2p---6 electron, 3s---2electron, 3p---6 electron, 4s---2electron, 3d---10 electron 4p---3 electron.. so the last electron enter in p ...which are 3 and other than this...no any electron wiil enter in p beacuse no. of electrons are less hence a is answer
