Question

2.8) Sometimes 2p orbitals are drawn as shown below; ماذا عمله لرنم هل سمون الى ان ار للمرء ممر لديها ما ليه دور What does this drawing represent? Does it suggest that the electron has finite probability of being found at the nucleus? We know that the probability of finding a 2p electron at the nucleus is zero. لنا من النواة ، فين مامان امان الفتور الکتروه مه 22 ,Is this a paradox ? Explain

Answer 1

It is the dumbbell structure of 2pz orbital. There are two lobes pointing in opposite direction from each other. An atomic orbital suggests or describe where an electron is likely to be found in an atom.There are nodes,where the electron density is zero.

We know that in case of a 2p orbital the probability of finding a 2p electron in the nucleus is zero. But in case of the 1s orbital,it is spherically symmetrical. So the probability of finding a 1s electron at any point depends only on its distance from the nucleus. The probability density is high at when r=0 (ie, at nucleus) and decreases steadily with increasing distance. Now when comes to the case of 2p electrons,it has a zero probability for finding 2p electrons in nucleus.
