All matter consists ofindivisible particles called atoms. ... Atoms cannot be created or destroyed. Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms. Atoms of same element can combine in more than one ratio to form two or...
and one electron and carry no electrical charge. The electron cloud is made up of particles calledelectrons, which carry a negative electrical charge and move in orbits or “shells” around the nucleus. Different atoms have different numbers of protons, neutrons, and electrons in their makeup. ...

If we can't see atoms, how do we know they're there? That's a very good question! Science is all about evidence, so what evidence do we have that atoms really exist? It comes in a variety of different forms: Chemists have long known that when we combine different elements in chemica...

make libquip: Compile QUIP as a library and link to it. This will make all the various libraries and combine them into one:build/${QUIP_ARCH}/libquip.a, which is what you need to link with (as well as LAPACK). A good starting point is to use thequipprogram, which can calculate ...
