Which ion has the smallest ionic radius Mg2 plus or Ca2 plus?

Mg is in period 3. Ca is in period 4. Down a group the size increases. So Mg is smaller than Ca.


What elements have a smaller atomic radius than strontium?

Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H


Which one is smaller mg or g?

mg is smaller than g. A mg is 1/1000 of a gram.


Is 07 mg smaller than 05 mg?

No No No


What is smaller mg or gram in diet?

A milligram (mg) is 1,000 times smaller than a gram.


How many ml are in 100 mg with a density of 12.5 mg?

As stated, this question cannot be answered because it gives the density as 12.5 mg. Density is measured not in mg but mg per some measure of volume. It could be 12.5 mg per litre (for a gas) or 12.5 mg per ml for a heavy metal or for even 12.5 mg per microlitre or smaller for matter from stellar corpses. IF you assume that the density is 12.5 mg/ml then since density = mass/volume volume = mass/density = 100/12.5 = 8 ml


Which is smaller mg or g?

A miligram is smaller than a gram.


Is 43 mg larger or smaller than 5 g?

Smaller. 1 gram = 1000 mg, so 43 mg = 0.043 g


What is less than ml?

mg is smaller than mL


How much is 9 mg liquid in ml?

You can not directly equate mass (mg) and volume (ml) without knowing the density of the substance being measured. For instance 9mg of liquid mercury would occupy a much smaller volume than 9 mg of water.


What does 2mcg equal in milliliter?

You cannot associate weight and volume directly without knowing density. If we assume density is 1 gram per ml, 2ug (micrograms) is going to equal 0.000002ml. This is because a gram will be a ml, a mg will be .001g and a ug is 1000 times smaller than mg


Who is more active Mg or Ca?

Ca is more active because it has an atom that is large. The larger the distance the smaller the force. If you want more information you should visit Which_is_more_reactive_Mg_or_Ca_Why
