PLEASE HELP ASAP PLEASE PUT THE ANSWER ON HERE NOT IN ANOTHER FILE THANKS The electron in a hydrogen atom can undergo a transition from n = 6 to n = 1, emitting a photon with energy 2.11 × 10–18 J. (2 points)

i. What is the frequency of this transition?

ii. How does this transition show that the energy of a photon is quantized?

C. Why is it impossible for an electron to have the quantum numbers n = 3, l = 0, ml = 1, ms = + ?

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
