Question

radioactive forms of rubidium chloride are used to help doctors evaluate how blood flows through a patients heart. write the chemical formula of rubidium chloride. refer to a periodic table and a list of polyatomic ions.

Explanation:

Step1: Identify ion charges

Rubidium (Rb) is in Group 1 of the periodic table, so it forms a +1 ion ($Rb^+$). Chloride ion ($Cl^-$) has a - 1 charge.

Step2: Determine chemical formula

To form a neutral compound, the charges must balance. Since the charges of $Rb^+$ and $Cl^-$ are equal in magnitude but opposite in sign, the chemical formula is $RbCl$.

Answer:

$RbCl$
