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
