What is the Heaviest and the Lightest things in the world?

Answer 1

Elements:

(Natural)
Mercury - most dense element
Hydrogen - least dense element

(Synthetic)

Urunhexium - densest element overall

Materials:

Toss up - Mercury could be considered a material, but there are steels and some other metals that have a greater density these days.

Lightest - Aerogel. At 99% air this silicone gel substrate is the lightest man-made material ever. It's like holding a solid cloud in your hand, you don't even know it's there.

Answer 2

On the Periodic Table of Elements, Hydogren is the lightest and Ununhexium is the heaviest.

Answer 3

Thing means elements? Heaviest - Mercury & Lightest - Helium

Answer 4

There are some styles of hardship-unfastened debris that haven't any mass, the main widespread of which being the photon. In different words, easy is doubtless certainly one of the lightest issues interior the universe. there's a theoretical style of particle that has detrimental mass, yet I won't get into all that. i don't comprehend if black holes could count form by way of fact the heaviest issues by way of fact it hasn't been desperate in the event that they are relatively "issues". they could be actually holes, or tunnels, or an entire host of alternative non-issues that have been theorized. If black holes do count form, the supermassive ones interior the centers of super elliptical galaxies are the main important issues interior the universe. If no longer, a megastar weighing approximately one hundred fifty photograph voltaic hundreds may be the heaviest single merchandise. around one hundred fifty photograph voltaic hundreds is the shrink to how heavy a megastar could properly be. The heaviest style of rely (consistent with sq. inch) is perhaps neutron degeneracy rely it relatively is the stuff that neutron stars are made out of. there's a theoretical quark degeneracy rely that is even denser and as quickly as returned there is the possibility that a black hollow relatively is a "subject" which might make that even denser, yet for now the neutron stuff is the superb we honestly comprehend approximately for valuable. in case you count form systems made out of diverse gadgets certain via gravity as "issues" the heaviest subject is a galactic supercluster. Lightest subject interior the international is, returned, easy. The heaviest subject is returned a rely of definition - the supercontinent it relatively is made out of Europe, Asia, and Africa ought to be the heaviest subject, or the pacific ocean ought to be the heaviest subject, or provided that all the oceans are linked that superocean ought to be the heaviest subject, or the middle of the Earth ought to be the heaviest subject (the middle is heavier than all something of the Earth blended).

Answer 5

I would think that the heaviest thing in the world is the world itself and the lightest thing would be 'nothing', a vacuum.

The words "Heaviest" and "Lightest" refer to the weight of an object, which in turn depends on the object's mass.
The amount of mass an object has depends on how "much" of it you have.
It is like asking,
"Which is heavier, a pound of rocks or a pound of feathers?"

I am sure you probably are referring to the property of density.
Density = mass / volume
The dense the object, the more mass it has in a smaller volume of space.

Answer 6

my mom is the heaviest and the lightest is origami is 5 time light than air

Answer 7

Heaviest-the earth
Lightest-Air

Answer 8

going to subtomic level, quarks should the lightest.
Meitnerium is the heaviest element.

Answer 9

i'm the lightest & my pooh is the heaviest. look out! chirp

Answer 10

Helium is Lightest
Mercury is heaviest
