Radium is element number 88 with the symbol Ra. Radium is an alkaline earth metal in group 2 of the Periodic Table. Radium is radioactive and very toxic.
Metal Beryllium is a light Metal of high thermal conductivity. Its melting point is high (1278 +/- 5 0 C) and boiling temperature 2970 0 C
Because plutonium is very toxic, radioactive, flammable and explosive.
Vanadium is a soft silvery white toxic metallic element used in steel alloys. Cobalt is a hard ferromagnetic silver-white bivalent or trivalent metallic element. Strontium is a soft silver-white or yellowish metallic element of the alkali metal group.
Assuming you mean by metal a workable metal as opposed to an element classified as metal, it is a hard question to answer because almost all metals can be toxic, in sufficient quantities. Gold and platinum are the two that are inert enough to be non-toxic. As to the others, the least expensive metal that resists oxidation and is relatively non-toxic would be nickel. Tho a percentage of the population shows a contact allergy to nickel.
it used to be lead, but most are steel now for environmental reasons. lead is a poison: a toxic heavy metal.
lead
Beryllium is an alkaline earth metal, atomic number 4, with a low density - 1,85 g/cm3, a natural element, toxic but very useful for many technologies.
Metal Beryllium is a light Metal of high thermal conductivity. Its melting point is high (1278 +/- 5 0 C) and boiling temperature 2970 0 C
Cerium
Tl is element 81 Thallium, a highly toxic poor metal.
used to be used in thermometers because it is the only metal that is liquid at standard conditions. Highly toxic, Mercury is an extremely rare element in the Earth's crust,
Uranium is a natural chemical element, solid, radioactive, unstable, having a great density, also atomic weight, with moderated reactivity, toxic, useful etc.
Mercury is an element. It has chemical symbol Hg. It is the only metal that is liquid at room temperature, and very toxic.
Fermium is an artificial chemical element, metal, toxic, radioactive, atomic number 100, etc.
Toxic lead is a metal that is found naturally on Earth. Toxic lead can interfere with bodily functions and cause damage to the liver, lungs, and heart.
Plutonium (Pu) is an artificial chemical element, metal, solid, toxic, radioactive.
Metal poisoning is a toxic accumulation of metals in the body. Some metal elements that are poisonous if ingested are mercury, lead, aluminum, arsenic and cadmium.
