What is the heaviest element in the universe?

uranium

What is the smallest particle of an element?

atom

What’s inside a quark?

A quark (/kwɔːrk, kwɑːrk/) is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei.

What is the shape of a quark?

The slowest quarks produce the spherical shape that physicists generally expected to see. Another shape — a flattened round form like a bagel — is sort of a cousin to the peanut shape with the high-momentum quarks.

Are quarks the smallest thing?

Quarks (along with electrons) remain the smallest things we know, and as far as we can tell, they could still be infinitely small.

What is the smallest possible size?

The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10-35 m across.

Are protons real?

One or more protons are present in the nucleus of every atom; they are a necessary part of the nucleus. Protons are composite particles composed of three valence quarks: two up quarks of charge + 23e and one down quark of charge − 13e. The rest masses of quarks contribute only about 1% of a proton’s mass.

Are protons actually round?

Based on theoretical calculations in nuclear physics and scattering experiments like those used to measure proton size, we know a proton is indeed spherical. These particles carry so much energy that they no longer just bounce off the proton.

What is quark color?

Quarks are said to come in three colours—red, blue, and green. (The opposites of these imaginary colours, minus-red, minus-blue, and minus-green, are ascribed to antiquarks.)

What are the six types of quarks?

Quarks were eventually found to come in six types, called up, down, charm, strange, top and bottom.

What color is a proton?

red
