Soft metal is more like just soft rock but heavy metal is like scremos and other REALLY HEAVY metal and black metal is REALLY REALLY HEAVY like they use death guturals and they are the hardest to understand.
That would depend on the use of the term 'trace elements'. In the analysis of something, say the human body, there are only small amounts "trace amounts" of some things. Selenium for example is poisonous in even small quantities, but in small 'trace' amounts it is used in some medicines. It is also found in some nuts.
In discussing all elements on earth, the phrase may mean that compared to other elements there is an extremely small amount of that element. The Curies processed tons of pitchblend (an ore containing uranium) to get milligrams of radium.
Every type of Metal is called Heavy Metal.
So Trash Metal is Heavy Metal
Due to their specific gravity
Boron is a heavy metal and if fairly are. There might be very small trace amounts of Boron in milk, though if there were they would be so small as to be inconsequential.

Yes - the steel under the rust is a metal (steel is iron with a trace of the non-metal, carbon), while the rust is iron oxide.
Muntz metal is a brass, which is 40% zinc and 60% copper, with a small amount of iron. There's no lead in it on purpose, but there will usually be trace amounts.
Yes Zinc is a trace mineral found in the human body, 2nd in quanity to iron
Boron is a heavy metal and if fairly are. There might be very small trace amounts of Boron in milk, though if there were they would be so small as to be inconsequential.
heavy metals are natural elements and are found in trace amounts everywhere and in everything. the problem is when they accumulate to more then trace amounts.
unknow right now....
Poisoning and disease can occur due to human exposure to trace quantities of heavy metals. Common trace metals include mercury (Hg), arsenic (Ar) and lead (Pb).
a stencil is a tracing paper which has different pictures you can trace. for example this animal he is a cut out for tracing in between of the animal is cut out so you can trace from inside it.

Muntz metal is brass with 60% copper, 40% zinc and a trace of iron.
comet is mainly ice, and so it leaves a trace as it gets close to the sun. meteors is not made of ice, but made of metal, solids, rocks, anything that doesn't melt easily and so it does not leave a trace or particles behind.
many people don't leave a trace behind. They are very hard to track.
glass and metal objects
the differences between a macromineral and a trace element is that their is no difference they both has something to do with the health
Parts of the bracelet won't leave a mark or trace of metal on the touchstone while testing is done on metal bracelets
