How do I make a model of Beryllium?
This sounds like a homework question to me, but I’ll still give you some information. Beryllium is a chemical element from the periodic table and has the symbol Be. Beryllium has an atomic number of four, which means it has four protons in it. It has one of the highest melting point of all the light metals, making it quite useful for various things: spot welding electrodes, springs, computer systems, nuclear weapons, the list is long indeed.
A model of this element would have a nucleus and four electrons rotating around it. Commonly atoms have as many electrons as protons. In the case of a Beryllium atom it may have four protons and five neutrons. This can be identified by its atomic mass, which is nine. The atomic mass is the total number of protons and neutrons.
Depending on how detailed your model should be it could simply look like this:
Note that the centre has five white spheres (the neutrons) and four red spheres (the protons). There are also the four electrons orbiting the nucleus.
