A photon with energy 2.87 eV is absorbed by a hydrogen atom. (a) Find the minimum n for a hydrogen atom that can be ionized by such a photon. 3 Correct: Your answer is correct. (b) Find the speed of the electron released from the state in part (a) when it is far from the nucleus. km/s

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
