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.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

gas

explanation:

smoke is the matter of a gas
