Homework Answers
B) Kr = 36 atomic number
36 + 2 + 10 + 4 = 52
1) atomic number = 52 = Tellurium = Te
2) electron belongs to Oxygen family
3) element is non-metal most of the p block elements are non-metals top to bottem metallic nature will increase
Te is metalloid
4) n = 5
l = 1
ml = +1
ms = +1/2 or -1/2
5) shape of orbital is dumble
