What is the most dense metal?
Osm ium is the densest of the elements. . The most dense pure metal is osmium, Os, with a density of 22.61 g/cm 3 (that's about twice the density of lead). Other very d…ense metals are: iridium, Ir, 22.56 g/cm 3 platinum, Pt, 21.4 g/cm 3 rhenium, Re, 21.0 g/cm 3 neptunium, Np, 20.4 g/cm 3 plutonium, Pu, 19.8 g/cm 3 gold, Au, 19.3 g/cm 3 tungsten, W, 19.3 g/cm 3 mercury, Hg, 13.53 g/cm 3 Lead, Pb, which is usually considered pretty dense, is only 11.4 g/cm 3 ! In case this isn't enough, lead will float on liquid mercury, which has a density of 13.5 g/cm 3 .
Potassium and Lithium Those two have densities less than water. Potassium has a specific gravity (or relative density) of 0.87. Lithium has an SG of about 0.53.
Metals have a tightly packed crystal lattice structure. Their nuclei tend to be more massive and can be more tightly packed due to their electrons being delocalized.
Osmium is the densest of the elements. The most dense pure metal is osmium, Os, with a density of 22.61 g/cm3 (that's about twice the density of lead). Other ver…y dense metals are: iridium, Ir, 22.56 g/cm3 platinum, Pt, 21.4 g/cm3 rhenium, Re, 21.0 g/cm3 neptunium, Np, 20.4 g/cm3 plutonium, Pu, 19.8 g/cm3 gold, Au, 19.3 g/cm3 tungsten, W, 19.3 g/cm3 mercury, Hg, 13.53 g/cm3 Lead, Pb, which is usually considered pretty dense, is only 11.4 g/cm3! In case this isn't enough, lead will float on liquid mercury, which has a density of 13.5 g/cm3.
Tungsten is the dense metal in fishing sinkers. Lead alloys are common, but lead is toxic.
The answer is either platinum or chengdeite depending on who you believe. Meaning, chengdeite has a specific gravity listed at various places as between 19 and 20, whereas oth…ers list pure platinum is listed between 18 and 20+. The reality is that there are some denser minerals that are enriched with iridium and/or osmium. Iridium, which is named after the element but usually, if not always, contains other elements as well, is the most dense (22.65) if you include enriched minerals. After reading much on the subject, I suspect that platinum is the best answer because chengdeite is extremely rare and therefore not enough has been measured to come to a conclusive determination of its mean specific gravity. There wouldn't be a need for this if chengdeite were a true element, but though it is classified as an element, in chemical reality it is an alloy, so the specific gravity can vary (presumably slightly, but there's not enough to say for sure) from piece to piece. The number represents weight in grams per cubic centimeter.
Dense metals tend to be used for things such as bullets. Commonly lead is used in bullets because it is once of the denser metals.
The most dense metals have densities of a little over 19 grams per cubic centimeter, Iridium and osmium are rare metals that are the most elements that exist. Gold is on…ly a little less dense than these metals and is probably the most dense metal the majority of people will encounter. Gary Benz Science Teacher American High school Fremont, CA.
The most dense the temperature should be is 4 degrees.
Lymph nodes are most dense in the inguinal, axillary and cervical regions of the body.
Earth is not the most dense planet. The density of Earth is only 5.515 g/cm3 , butthe density of planet Kepler-70b (in the Cygnus constellation) is 64 g/cm3 ! See Sources and …related links below.
The high density of most metals is due to the tightly-packed crystal lattice of the metallic structure Wikipedia.org
Troposphere is the most dense part because it is at the bottom of the atmosphere.
