Be sure to answer all parts. Rubidium and bromine atoms are depicted at right. Answer the following questions. (a) What is the charge on the rubidium ion? What is the charge on the bromide ion? (b) To which noble gas is the rubidium ion related? To which noble gas is the bromide ion related? h5sil8102 (c) Which pair below best represents the relative ionic sizes?

The complete question is found on the image attached.

a) Rb= +1, Br= -1

b)Bromide and rubidium ions are related to krypton

c) C

Explanation:

Rubidium is found in group 1 with a charge of +1. Bromine is found in group 17 with a charge of -1. Both species have the same configuration as krypton. The ionic sizes of the ions are a very similar to each other Rb+ is 166 while Be is 167.

This RbBr is an ionic compound.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
