chemmie's question
 

:D Hi Admin,
I'm wondering if you can help me out with something.You see, I've been asked by my online homeschooling system to "adopt a element", and I need some info, so can you help me find the heating, melting, cooling,density,
color, state,symbol, atomic number, atominc mass,number of protons, nuetrons, and electrons of thr element krypton?

Also, who discovered it, and when? AND, the uses of it? Sorry if I'm asking too
much, but the system recommended your website, so, can you help me?

chemmie,

i'ts also important that you know how to do it yourself. in the periodic table, there are lots of information about krypton. the mass and atomic numbers are definitely there. you can consult the legend in the periodic table for easy look up. if you still don;t know how to determine the number of subatomic particles krypton has, get back to me and i'll teach you. but i want you to look at the periodic table first. get back to me asap if you still can't find what you need.
