Determine which have noble gas configurations

A sample of neon effuses from a container in 80 seconds. The same amount of an unknown noble gas requires seconds Identify the gas. Which of the following acids would have the highest electronegativity?

PH3 B. HCI C. H2SO4 D. H25 What is the major different between the particles in a liquid and a gas of the same substance at the same temperature? Write electron configurations for the following ions, and determine which have noble-gas configurations. Type your answer using the format [Ar] 4s2 3d10 4p2 for [Ar]4s23dp2.

Which noble gas would be expected to show the largest deviations from ideal gas behaviors, He, Ne, Ar, Kr, or Xe? Would it be He? I'm not sure how one would determine this.

Video transcript - [Voiceover] In this video, we're going to be talking about how you can write electron configurations using noble gas notation.

And to be more specific, in this video we're also going to be focusing on examples using main group elements. So, we're doing that because the transition metals, right here, and the lanthanides, are a little bit more complicated, so we won't be doing that in this particular video.

So the rule for writing the noble gas notation for something is pretty simple. It is, you take the noble gas immediately preceding your atom or ion, so what do I mean by immediately preceding? That means we want the noble gas that comes right before it, so you go up a row, and you go over to here, where the noble gases live. And you put that in brackets and then you write your other electrons, and you write your other electrons using the same notation that you normally write electron configurations in.

It does not have noble gas configuration, if it did it would have exactly the same configuration as Kr, with no extra electrons. In this case, O2- has the same numner of electrons as Neon, the noble gas at the end of the period, so the configuration can be written. Your email address will not be published.
