an empirical formula
For an ionic compound, the empirical formula is called a formula unit.
Coordination number of an ion is the number of oppositely charged ions present around that ion as the neighbour ions , in that ionic crystal.
I would not think so as their natural state radius is so close. Ca(2+) loses two electrons, so I think it would have the smaller ionic radius.
Milli equivalents and milli moles are units used to describe molecular or ionic grades of concentration. A milli equivalent or mEq is derived by dividing the concentration in millimol or mmol by the valency of the ion involved.Eg: 1 mEq of sodium Na+ = 1 mmol of sodium (because valency is 1)whereas 1 mEq of Ca2+ = .5 mmol of calcium. (because valency is
Abstract Envelopes of a marine isolate, c-A1, and of a terrestrial isolate, 121, were compared for their susceptibility to disintegration in distilled water after exposure to 0.05 m MgCl2 and to 0.1 and 1.0 m NaCl. After exposure to MgCl2 alone, both types of envelopes remained intact in distilled water. Envelopes of marine isolate c-A1, but not of the terrestrial isolate, fragmented in distilled water after exposure to 1.0 m NaCl. Partial reaggregation of the c-A1 envelope fragments occurred on addition of MgCl2. In cation-exchange experiments, bound Mg++ in the envelopes of both organisms was displaced by Na+. The envelopes of c-A1 were found to contain lipopolysaccharide, muramic acid, and a variety of phospholipids, of which the major component was phosphatidylethanolamine, accompanied by lesser amounts of phosphatidic acid, diphosphatidylglycerol, and phosphatidylserine. Analyses of envelope acid hydrolysates revealed a similar amino acid distribution in the marine and terrestrial isolates, but envelopes of c-A1 had less than half the total amino acid content of envelopes of 121 per envelope dry weight. Possible relationships between cations and biochemical components of the envelopes are considered in terms of differences in behavior of the two organisms in low ionic environments.
It is a formula unit.
No. The chemical formula of an ionic compound is a formula unit and represents the lowest whole number ratio of ions in the compound. Ionic compounds are not made of molecules.
An ionic compound is written by using the lowest ratios of the ions in a compound. E.g. magnesium chloride is not Mg6Cl12, but MgCl2.
This is an ionic compound, for example a salt as potassium chloride.
SO3 is a covalent compound, not ionic. It is called sulfur trioxide.
This is called ionic bond.
A compound composed to two oppositely charged atoms is an ionic compound/salt.
Sodium chloride is formed by an ionic bond.

We need to balance the number in an ionic compound b/c Ionic Compounds must be Neutral which means that is No Charge=0
What you write for an ionic compound is called the formula unit, but the formula unit is almost always the same as the empirical formula. The answer to your question could not be the molecular formula because an ionic compound is not a molecule.
