ununoctium is the heaviest substance...
Ununoctium (i /uːnuːnˈɒktiəm/ oon-oon-OK-tee-əm),[8] also known as eka-radon or element 118, is the temporary IUPAC name[9] for the transactinide element having the atomic number 118 and temporary element symbol Uuo. On the Periodic Table of the elements, it is a p-block element and the last one of the 7th period. Ununoctium is currently the only synthetic member of Group 18. It has the highest atomic number and highest Atomic Mass of all discovered elements.
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.

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.
The weight depends upon the mass of the planet. A larger planet has a larger gravitational 'pull', hence Jupiter, being of a great mass objects will weigh the heaviest. To calculate your weight on other planets go to the website below, under 'Related links'.
In astronomy, heavy, heaviest etc. is never used as that is a terminology for weight. Weight is a function of an objects mass and the amount of gravity. This is why you would weight 120lb on Earth but only 20lb on the Moon. We therefore use the terminology "mass" as it does not have to take gravity into account. So the most massive planet is Jupiter have more mass than any of the other planets. [See related question]
yes it is the heaviest planet
Jupiter is the biggest and heaviest planet.
No, gold is not the heaviest substance. While gold is dense, there are heavier substances like uranium and platinum. The weight of a substance is determined by its mass and volume, so density plays a major role in determining which substance is the heaviest.

Yes
In our solar system, the largest planet, Jupiter, is indeed also the heaviest, weighing in at about 317 times the mass of Earth. However, a larger planet isn't necessarily a heavier one - for example, Uranus is larger but less massive than Neptune.

It is 7th. (Strictly speaking you should say most massive, not heaviest.)
