Now, switch to the Rutherford Atom tab at the bottom of the screen. In the upper left, click the red and gray cluster. This model represents the positively charged nucleus.
If this model of the atom is correct, what should happen to the alpha particles as they pass through the atom?
O All of the alpha particles should pass through the atom without changing direction.
o As the alpha particles approach the electrons, the electrons should absorb them.
O As the alpha particles approach the electrons, the particles should be deflected away from the electrons.
The alpha particles that come close to the nucleus should be deflected away from the nucleus.

Answerthis solution will not form a precipitateexplanationsolubility equilbrium:         pbf₂(s)  ⇄ pb²⁺(aq) + 2 f⁻(aq)the solubility product expression is    (we exclude solids from the equilibrium expression).now suppose we have the trial ion product q, which we can define as    then, we can interpret  q as the product of the concentration of the ions that we have and ksp as the product of the ion concentrations that are needed to form a saturated solution.if q > ksp, then that implies that there will be a surplus of ions that exceed the amount that is required to form a saturated solution. a precipitate will then form (the precipitate continually  forms until the surplus ions are removed and q is decreased to ksp's value).if q = ksp, the saturated solution that forms is barely saturated and the precipitate will be minimal.if q < ksp, then the ion concentration will not be enough to form a saturated solution (so no precipitate).using our information, we calculate the trial ion product:     since q = 2.7  × 10⁻⁸ < ksp =  4  ×  10⁻⁸, a precipitate will not form.
