Crafting atoms

After the big bang, the only atoms that formed spontaneously in the universe were hydrogen and helium. In elementary craft only these atoms can be crafted on the grid.

Larger atoms can only be made in the universe under extreme conditions such as high pressure and high temperature.

In ElementaryCraft, higher atoms do not exist yet.

The hydrogen atom
A hydrogen atom is crafted with three different particles:

Hydrogen: 1 proton + 1 electron + 3 photons

The photon illustrates the Coulomb force through which the electrically charged proton and electron attract each other.

Dive deeper into the physics: the hydrogen atom
The electrically neutral atom contains a positively charged proton and a negatively charged electron, which is bound to the nucleus by the coulomb force (transferred by photons). The most abundant isotope (also called hydrogen-1 or light hydrogen), does not contain neutrons; other isotopes of hydrogen, such as deuterium and tritium, contain one and two neutrons, respectively.

In the "solar system model" hydrogen looks like this.

The solar system model is not correct according to quantum mechanics, where one can only indicate probability densities to find the particles somewhere when one would measure them.

But for Minecraft, the solar system model is enough.

The helium atom
A helium atom is crafted with the same particles, but more of them:

Helium: 2 protons + 2 neutrons + 2 electrons + 3 photons.
