What is silicon? Atoms, elements, chemistry

Diagram of a silicon atom When a red giant star is getting older and runs out of helium fuel, it starts to convert the oxygen atoms in the star into silicon atoms. All silicon is made this way, inside a red giant star. Silicon is heavier than oxygen, because oxygen has only eight protons [...]

What is oxygen? Atoms, elements, chemistry

Diagram of an oxygen atom When a star has changed all of its hydrogen atoms into helium, it turns into a red giant and moves on to convert the helium atoms into carbon atoms and oxygen atoms. All of the oxygen in the universe starts out inside stars. Then when all the helium is used up, [...]

What is a meson? Definition of a meson – Chemistry

A meson is much smaller than an atom! These are lithium, cobalt, and oxygen atoms (as in a lithium-ion battery), seen under an electron microscope from Berkeley Labs. What is a meson? Mesons are tiny sub-atomic particles. Sub-atomic means they are smaller than atoms. They form out of quarks in high-energy situations. How [...]

What is mercury? Atoms, elements, chemistry

Diagram of a mercury atom. Thanks to Open Door for this image Along with gold, lead, and uranium, mercury is one of the heavier kinds of atoms. Every atom of mercury has 80 protons and 121 neutrons in its nucleus. Like those atoms, all mercury atoms are made inside older stars that have [...]

What is lead? Atoms, elements, chemistry

A lump of lead As with all of the other heavier elements, all of the lead in the universe came originally from inside stars. Lead is the heaviest atom that is still stable, with 82 protons and 125 neutrons, just a little heavier than mercury. Unlike many other metals, lead does not conduct electricity [...]

What are atoms? Simple science – Chemistry

By |2018-05-31T11:49:28+00:00June 2nd, 2017|Chemistry, Physics|

Lithium, cobalt, and oxygen atoms (as in a lithium-ion battery), seen under an electron microscope from Berkeley Labs Atoms are collections of tiny bits of matter, particles which we call protons, neutrons, and electrons. These particles are made of even smaller particles called quarks. But even protons, neutrons, and electrons are so small you [...]

Copper – Atoms, Elements, and Chemistry

Diagram of a copper atom Copper is a kind of atom that has only one electron in the outermost ring. Copper is a fairly heavy atom, that can only be made inside a red giant star. When the red giant star has finished making copper and moved on to heavier kinds of atoms, [...]
