Elemental: The magnesium itself; the rest of the compound weight is the partner molecule.
Compound: The whole salt, such as magnesium glycinate, that must physically fit in the capsule.
Size 000: The largest standard capsule, about 1,100 mg of powder at 0.8 g/mL, the top of the usual 0.6–0.8 range; size 00 holds about 730 mg and size 0 about 545 mg.

How much citrate compound is in one serving?
Vitamin World Magnesium Citrate 200 mg carries 1,238–1,770 mg of magnesium citrate per serving for 200 mg of elemental magnesium, against 1,100 mg in the largest standard capsule; capsule capacities do not apply to this other (e.g. tea bag).

The filed salt can have more than one hydration state (trimagnesium dicitrate 16.2%; dibasic and hydrated forms as low as 11.3%), so the compound mass is a range.

How much elemental magnesium is actually in this label's filed magnesium lines?
Vitamin World Magnesium Citrate 200 mg files 1 magnesium line in NIH DSLD 62794; the selected primary line declares 200 mg of elemental magnesium per serving, against 0 other rows excluded from the primary amount. A salt named under another nutrient does not turn that nutrient's quantity into elemental magnesium.
