electron: the negatively charged particles held in <em>orbital shells </em>around the nucleus. They are held in place by <em>protons.</em> <em>Electrons </em><em />do not effect the <em>atomic weight </em>but they do effect <em>the charge.</em>

proton: the positively charged particles found in the nucleus. <em>Protons </em>do effect <em>the atomic weight</em> and <em>the charge. </em>

neutron: the particles without any charge found in the nucleus. <em>Neutrons </em>do effect <em>the atomic weight </em>but do effect <em>the charge. </em>

The three particles of any atom are
<u>electron</u>) the smallest particle and is held in shells around the nucleus of the atom
<u>proton</u>) is found in the nucleus and is much larger than an electron
<u>neutron</u>) the same mass as a proton and also found in the nucleus of the atom

Of the five salts listed below, which has the highest concentration of its cation in water? assume that all salt solutions are s
Zigmanuir [339]
First of all, I need to know what these five salts are. Luckily, I found a similar problem from another website which is shown in the attached picture. The Ksp is the solubility product constant. It follows the formula:

Ksp = [cation concentration]ᵃ[anion concentration]ᵇ
where a and b are the subscripts of the metal and nonmetal, respectively. 

For the solutions ahead, let x be the concentration of the cation.

A.  The formula is PbCr₂O₄.
2.8×10⁻¹³ = [x][x]
Solving for x, x = 5.29×10⁻⁷ M

B. The formula is Co(OH)₂. 
 1.3×10⁻¹⁵ = [x][x]²
Solving for x, x = 1.09×10⁻⁵ M

C. The formula is CoS. 
 5×10⁻²² = [x][x]
Solving for x, x = 2.24×10⁻¹¹ M

D. The formula is Cr(OH)₃. 
 1.6×10⁻³⁰ = [x][x]³
Solving for x, x = 3.56×10⁻⁶ M

E. The formula is Ag₂S. 
 6×10⁻⁵¹ = [x]²[x]
Solving for x, x = 1.82×10⁻¹⁷ M

<em>Thus,the highest concentration is letter B, Cobalt (II) Hydroxide.</em>
