Hello, My daughter is doing this project for school and has answered over 100 of the 135 questions. We have several that we cannot find or s
answer and need help. Thank you for your time.
41. an elment or alloy whose electron configuration ends with nd4.

37. and electron stream distorter

48. a substance with boiling point less than 295 Kelvin

please at the very least show what are your thoughts so far or what u've done so far; it goes against forum policy for us to your homework for you.

have looked in chemistry book, have searched the web, have looked at the periodic tables and electron configurations but cant seem to find one with that configuration and cannot find a site with the configurations for the alloys. am confused by the nd4 ending.  not clear on what the teacher wants for electron stream distorter (like a tv or something) but they wont supply any more information. Not sure what would boil at such a low temperature and not sure how to find out.

hint 1: n stands for a digit

hint 2: what form takes liquid after boiling? Look around - what you don't see is what you are looking for

For "electron stream distorter" they may be refering to something which can exert a force on a moving charge.  See if that interpretation leads you to a common material.
