If I am not mistaken, the gravity of an object is determined by its mass, and that is what makes it heavy. Size does not always make an object heavier. For example, the planet Jupiter is much larger than earth, but it is less dense and contains no solid matter. Therefore it weighs less and has less gravity.

If they were big I wouldn't be able to do that.

Are calcium gluconate magnesium sulfate and potassium phosphate heavy metals?
No. These are not heavy metals. They are salts of non heavy metals.
Does well water have heavy metals?
It can have small amounts of heavy metals, depends where it comes from. - If you are concerned take a sample for lab analysis.It can have heavy metals, depends where it comes from. If you are concerned take a sample for lab analysis.
What is the difference between heavy metals and the other metals?
Scientifically speaking, there are a couple of fundamental differences between heavy metals and other metals in the table of the elements. Heavier metals tend to have more ions and typically, less toxic elements.
Why are heavy metals toxic to life?
Most heavy metals, but not all, are not even required by human body and they cause problems even in a very small concentration. They often take same pathways as essential nutrients and so cause toxic effects. They also bioaccumulate and biomagnify
Is nickel a heavy metal?
No. Heavy metals include things like Lead (Pb)
Why you feel so thirsty when you smoke a cigarettes?
heavy metals
Are calcium gluconate magnesium sulfate and potassium phosphate heavy metals?
No. These are not heavy metals. They are salts of non heavy metals.
Where are heavy metals found in the periodic table?
Heavy metals are typically found in the middle of the periodic table. These heavy metals are often also transition metals.
Why are electromagnets used for picking up heavy metals?
Well electromagnets have great power so it is understandable that someone would use it to pick up heavy metals.
What are the advantages and disadvantages of using incineration to dispose of heavy metal?
The disadvantage is that you can't destroy heavy metals (or any metals or, indeed, any chemical elements) by incineration. So the most you can achieve by incineration is scattering heavy metals around with ash that is carried away with smoke.
What are the importance of heavy metals in cooking?
Heavy metals compounds have frequently toxic properties.

Why are lead and mercury considered heavy metals?
they are considered heavy metals because of the weight to volume ration in comparison to other metals. they have more mass with little volume than other metals do.
What heavy metals can be found in crude oil?
Easy answer you could have come up with by yourself I think. Crude oil, means oil straight from the ground and not refined yet. Heavy metals means not light metals. So not iron or sodium but Lead and other heavy stuff. Since oil comes from the ground and metals are mined from the ground, it makes sense that they could be found together. So if the teacher wants a different answer he should have said "how is crude oil formed" or something like that.
What heavy metals that can be taken up by plants?
The metals having density more than 5 are usually known as heavy metals. Density of some heavy metals is as below: Zinc (Zn) 7.13 Iron (Fe) 7.87 Copper (Cu) 8.96 Silver (Ag) 10.49 Lead (Pb) 11.36 Mercury (Hg) 13.55 We use fertilizers which contain elements having density more 5 or more than 5 like zinc sulphate or copper sulphate ets. so we can say that plants take these heavy metals in shape of fertilizers.
