Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.May 22, 2013
The information that should be added to the chart in order to find out who ran a greater distance is THE UNITS USED TO MEASURE DISTANCE EACH DAY.
In science, the use of units if very important and each record made must be accompany with relevant units that are appropriate for the measurement taken. If units are not used along with data, it will be very difficult to quantify the values that are recorded. Scientists all over the world use SI units in their works in order to ensure uniformity.
1) • Solubility is the ability of a substance to be dissolved especially in water
• Unit; mg/L (milligrams per liter)
2) A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent.
3) To detoxify any acid that was previously used in it

The neutral atom of lead must have 82 protons while ions can have b or less than 82.
The atomic number of an element is the number of protons in the nucleus of the element.
Also, for neutral atoms, the number of protons equals the number of electrons.
In ionic form, the number of protons/electrons of an atom may vary and be different from that of the neutral form.
Positive charges mean that the ion has less proton than its neutral version while negative charges mean that it has more electrons than its neutral version.
Thus, the neutral atom of lead will contain an equal number of protons as the electrons while its ionic form can have more or less than 82 protons.
