Evaluate r), the expectation value of r, for the 2p state of the hydrogen atom. in a separate calculation determine the distance from the nucleus where the probability of finding the electron in the 2p state is at its maximum. what is that distance for he? hint for this problem it is easiest to start with the radial function, r,(r), written explicitly for any nuclear atomic number z

Astudent made the lewis dot diagram of a compound shown. what is the error in the lewis dot diagram? a)an o atom should transfer all of its six electrons to mg because the formula is mgo b) both electrons of mg should be transferred to one o adam because the formula is mgo c) the electrons should be transferred from each o add him to capital mg because mg has fewer electrons d) the number of dots around mg should be four because it has to transfer two electrons to each o
