Well, the IUPAC calls the heavy metal "meaningless and misleading" because there is a lack of a "coherent scientific basis". However, heavy metals usually refers to metals that are damaging to organisms or environments in excess concentrations.
This is because heavy metals are those metals having a neutron is to proton ration equal to or greater than 1.5
Lead has 82 protons and 125 neutronsn/p=125/82
=1.52
Mercury has 80 protons and 121 neutronsn/p=121/80
=1.51
Hence lead and mercury are heavy metalsBecause the term copper was already taken, um jk
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.
Because of higher density than the water and high molecular weight, they are called heavy. But some called them heavy because of the toxicity they cause.

Mercury ------ Strontium (including the radioactive isotope 90Sr); also cadmium.
Mostly it is considered that heavy breathing is a result of some heavy physical exrcise like Running.But actually it is a result of internal system's usage as a response against any series of incidents/acts.Like when u r eating, or youare in a state of big threat, or sexual intercourse
Do you breathe metal? Oxygen is a gas, not metal.
Radioisotope labelled metal ions can be used to examine the availability of different fertilizer components for use by the crops. Similarly mercury or some other undesirable substances can be applied. If the crops take up the label then it shows a potential problem.
Drill the tree till you can see the center of the tree and inject mercury!
No.... Aerosmith is not considered "heavy metal". Although some of their songs came close to it.... But none of their music is considered heavy metal.
Yes, mercury is a heavy, silvery metal that is liquid at normal temperatures.

Mercury is a metal that is liquid at room temperature. It is also poisonous.
Yes mercury is very dangerous. It is considered a 'heavy toxic metal' if it is in your body. High amounts of mercury has caused major diseases such as Alzheimer's which is the complete or major loss of memory.
Steel is an alloy consisting mainly of iron, which is metal, but not heavy metal. Heavy metal means toxic metals like mercury, lead, plutonium and uranium
mercury in the flesh of the fish it contains a high amount of mercury was a heavy metal that can be toxic to human
No, mercury is a harmful heavy metal toxin that impairs mental function.
As a metal, it is liquid at room temperature. Also, it's a heavy metal.
Mercury is a heavy metal, it will sink in sea water.
Is a very heavy liquid and doesn't wet glass
It is toxic and can cause heavy metal poisioning
