> Mercury belongs to the 12th group and 6th period. It has symbol as Hg and its atomic weight is 80.It has isotopes as 202Hg and204Hg with mass of 200.59 u. > … So from all above, the lightest metal is Lithium with atomic weight as 6.941 u, therefore option C is correct.
Which are the lightest metals?
The first seven metals in the periodic table are lithium, beryllium, sodium, magnesium, aluminium, potassium and calcium, known collectively as the “lightest metals”.
What is the lightest metal on the periodic table?
Students may or may not remember the density of each metal but students must remember that lithium is the lightest metal in the periodic table.
Which is heaviest metal?
Osmium is one of the heaviest materials on earth, weighing twice as much as lead per teaspoon. Osmium is a chemical element in the platinum group metals; it’s often used as alloys in electrical contacts and fountain pen nibs.
Which is the lightest and heaviest metal?
Heaviest Metal by Relative Atomic Mass
Oganesson (atomic number 118) is the heaviest element on the periodic table, but it is a synthetic element that can’t be observed in nature. Lithium (atomic number 3, relative atomic mass 6.941) is the lightest metal in terms of relative atomic mass.
What is the cheapest and strongest metal?
The cheapest metal is Iron, strongest natural metal is Tungsten, hardest metal is Chromium, and the lightest metal is Microlattice on earth.
Which metal is lighter than water?
The lightest or least dense metal that is a pure element is lithium, which has a density of 0.534 g/cm3. This makes lithium nearly half as dense as water, so if lithium was not so reactive, a chunk of the metal would float on water.
What is the lightest thing in the world?
Graphene Aerogel, world’s lightest substance.
Which metal is less dense water?
lithium, sodium and potassium are less dense than water so they float on the surface of the water. the metals move about the surface of the water and fizz as hydrogen gas is produced.
Which is the hardest metal?
In terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact. Titanium, on the other hand, has a tensile strength of 63,000 psi.
What is the cheapest heaviest metal?
Lead is probably the cheapest and most readily available of denser metals. It’s available for sale in stores worldwide for use in everything from plumbing and electrical work, to fishing tackle.
Can osmium kill you?
Osmium Tetroxide is toxic, volatile, water soluble, and really wants to kill you. Don’t do it. … Unfortunately, Osmium forms a nasty compound, Osmium tetroxide , when exposed to air. Osmium Tetroxide is toxic, volatile, water soluble, and really wants to kill you.
What is the heaviest metal song ever?
At the end of 2009 the track ‘Hunting & Gathering (Cydonia)’ from SunnO)))’s ‘Monoliths & Dimensions’ was named the Heaviest Song of All-Time by American radio DJ Jason Ellis. This is as may be but you need to go to the beginning of their career to hear the album so heavy that it created its own weather system.
What are the 10 heaviest metals?

Which is the heaviest metal gold or silver?
The answer is gold, which is why smaller gold objects feel heavier when compared to silver objects of the same size. Density or specific gravity depends on the size of the nucleus of the atoms. A single atom of silver has a total of 47 protons and electrons and 61 neutrons.
What is the heaviest thing on earth?
According to Guinness, the Revolving Service Structure of launch pad 39B at NASA’s Kennedy Space Center in Florida is the heaviest thing that’s ever been directly weighed. It measured at about 5.34 million pounds or 2,423 tons.
