Answer:
the ion with the most electrons
Explanation:
Ionic size generally depends on weather the ions are negative or positive. Averagely, atoms become smaller on moving from left to right in the periodic table. A movement from left to right in the periodic table leads to a gradual increase in the number of electrons and decrease in atomic size. Li+, Be2+ and B3+ are all isoelectronic but B3+ is the smallest ion.

Hope this help
Any given experiment has numerous control variables, and it's important for a scientist to try to hold all variables constant except for the independent variable. If a control variable changes during an experiment, it may invalidate the correlation between the dependent and independent variables.

Answer:
S MgCO3 = 1.8708 E-4 M at 25 °C
Explanation:
S S S
⇒ Ksp = 3.5 E-8 = [ Mg2+ ] * [ CO32- ] = S * S
⇒ Ksp = 3.5 E-8 = S²
⇒ S = √3.5 E-8
⇒ S = 1.8708 E-4 M
Explanation:
So copper is a lattice of positive copper ions with free electrons moving between them.
