Helium.
The Schwarzchild radius of a 2 solar mass black hole would be about 5.9 km.
I suppose that you think to a "solar flare".Coronal mass ejections are bigger than solar flares.
Betelgeuse is a type M Red Supergiant with a probable mass between 10 and 20 solar masses. Because of its mass it will continue to fuse elements until it reaches the iron phase at which time it will explode as a Type II supernova probably leaving behind a Neutron star of about a 20km radius.
The stars solar mass, or relative size to the sun. If its gravity is big enough, when it does condense in on itself, it will create a black hole. If not, it will form a highly dense clump of matter, or a Neutron Star If the stars mass is more than 3 solar masses, it will form a black hole. If it is less, it will form a neutron star
... more massive (it has more mass).... more massive (it has more mass).... more massive (it has more mass).... more massive (it has more mass).
The heaviest term for mass that I've ever came across is a Solar Mass. As in the star Beta Pictorus is said to be 1.5 solar masses.
Ununseptium and Ununoctium are currently tied.
Jupiter, with a mass 318 times that of the Earth.
In our solar system, the planet with the most mass is Jupiter. So, if the planets could be arranged with their centers all at the same distance from, say, the center of the sun, then Jupiter would be the heaviest in that situation.
This element is ununoctium - atomic number 118; uuo is an artificial element. I suppose that you think to atomic mass and not to density.
The heaviest (hevest?) naturally occurring element is Uranium (238 a.m.u.) but the heaviest known element is atom number 114, 117 or 118, the exact mass being unknown but over 250.
Francium is the heaviest of the alkali metals, with an atomic mass of 223 grams.
Uranium - atomic weight; 238,02891 But now it is more correct to consider plutonium as the heaviest natural element (mass: 244 for the isotope 244Pu).
Ganymede, the largest moon of Jupiter with a mass of 1.4819 x 1023kg
Yes, uranium has the heaviest atomic mass between natural elements (238,02891).
If you mean mass, then the answer would be no. Within our solar system, Jupiter has the greatest mass at 1899x1024kg, while Earth is the fourth most massive at 5.97x1024kg.
no its the diamond we did it at school the othere term :P fail
