Sodium ions have a +1 charge, whereas calcium ions have a 2+ charge.
It would be unethical to use this service to answer exam or graded questions. CaCl2 + 2NaOH --> 2NaCl + Ca(OH)2 Calcium Chloride + Sodium Hydroxide --> Sodium Chloride + Calcium Hydroxide Why: Ca ion has 2+ charge Cl ion has 1- charge Na ion has 1+ charge OH polyatomic ion has 1- charge
A calcium ion has two positive charges compared to only one for a sodium ion. Therefore, the positive charge density of a calcium ion is higher and correspondingly better able to increase the polarity of the covalent bonds in the water molecules, thereby the reducing the energy of the solution as a whole.
The sodium ion (Na+) is a cation (positive charge) and the fluoride ion (F-) is an anion (negative charge).
While a sodium ion and neon atom both have 10 electrons they are of different elements as a neon atom has 10 protons while sodium has 11. As a result the neon atom is neutral while the sodium ion carries a positive charge. So neon can exist on its own as a gas while sodium ion needs a negative ion to balance its charge and form an ionic solid.
I actually don't think it does. Diffusion is normally controlled by mass, and sodium atoms being less massive than chlorine atoms should diffuse more rapidly (the difference in mass between the neutral atom and the ion isn't enough to matter).
Calcium ion
Sodium ion is larger than magnesium ion. The electrons are more tighly bound in Mg2+. On a "diagonal relationship" Li and Mg are similar in size as are sodium and calcium
Chloride is an ion of chlorine plus one electron. In solution, calcium is an ion missing two electrons.

CaO - the attraction between a 2+ and a 2- ion is much stronger than between a + and a -.
The difference in mass between a sodium atom and a sodium ion (supposing Na+) is 9.10938188 × 10-31kg (the mass of an electron). This is due to the sodium atom losing an electron to form an ion. In order to attain the mass of a single sodium atom you need to divide the molar massn (mass number) of sodium by avogadro's number. You can then find the mass of the ion by subtracting the mass of an electron from the mass of a sodium atom.

Sodium in one, but so are potassium and calcium.
Salts made of a metal and a nonmetal are named this way: [metal] [nonmetal root]-ide Examples: sodium + chlorine = sodium chloride potassium + iodine = potassium iodide Salts made from a metal or other complex cation and a nonmetal or other complex anion are named based on the cation and anion names: ------------------------------- ammonium ion + hydroxide ion = ammonium hydroxide sodium ion + hypochlorite ion = sodium hypochlorite calcium ion + chloride ion = calcium chloride
