so which is the correct way of increasing radius and what is a Te=

Lauren
Arrange the members of each of the following pairs in order of increasing radius and explain the order: A. Te, Te2- B. Al, Al3-

What I dont understand is where I get the number of dots from and what is the electron configuration

Lauren
Write the electron configuration of Sn and Sn2+ Give the electron configuration of Cu+ and Cu2+

Lauren
For each of the following, write the electron configuration and Lewis symbol: A. In B. In- C. K+ D. I-

Lauren
How do I figure out how to write the lewis symbol for the following A. Br B. Br- C. Sr D. Sr2+

question for Dr.Bob22
i get how you get X = 2.077*Y, but i dont understand how if you plug in 0.481X in for Y to solve for x. x = 2.077(0.481x) x = 0.999x then what??? i know this is probably a simple stupid math question, but i need to do another problem like this and i'm stuck at this part...

question for Dr.Bob22
The mole fraction of acetic acid (CH3COOH) in an aqueous solution is 0.675. Calculate the molarity of the acetic acid, if the density of the solution is 1.0266 g mL-1. To give a different take on this, here is another way of approaching the problem. I don't claim it is bet...
