but the element Zr is on the fifth period, so wouldn't it have an "n" value of 5, which makes ml +4 possible?

I am still totally confused about the principle quantum number even though i got passed the unit with a A+ on the exam. does the principal quantum number, n, have anything to do with the period? Does the "n" value, which leads to the "l" and "ml" actually indicate all the possible orbitals for a...

[SOLVED] Is it the protons or electrons that are responsible for an element's propert On a chemistry test I took, there was a question that asked "What subatomic particle is responsible for an element's physical and chemical properties"? I picked the "proton" as the answer choice, but the...

for my science fair project, i am designing an experiment that tests the potency of the gas carbon dioxide, methane, CFC, and ozone in their retention of heat. I will three use three balloon (the balloons act as the ozone layer) and put in each one of them a pile of heated dirt. Then, i will...

My answer was wrong.:confused: I'm guessing there's another method to solve this, like plugging in numbers... Instead of making X the unknown value, i used "a" .

Ok. Thanks :) that's all I need to know.

I hope this question isn't too lame for this forum.:!) If Earth is the only known planet with the probable condition for life existence, is it possible for a cup of milk to form yeast after several weeks when you placed it on the surface of other planets in our solar system, such as Mars...
