Which statement accurately describes the location and charge of the electrons in an atom?

the electrons are inside the nucleus and have no charge

the electrons are outside the nucleus and have no charge

the electrons are inside the nucleus and have a negative charge

the electrons are outside the nucleus and have a negative charge

The electrons are outside the nucleus, they are on whats called electron shells (orbitals) and have a negative charge.

The electrons are outside the nucleus and have a negative charge

Adozen is 1221/12 = 1.751.75 x 12 = 21therefore, 1.75 is the answer.

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.
