Silicon-29 has 14 protons (atomic number), 14 electrons if the atom is neutral, and 15 neutrons (mass number - atomic number).

What does an atom do?

An atom moves, in three ways: translational, rotational, and vibrational. Atoms usually combine with other atoms, of the same or different elemental type, into different forms of matter. Every atom has a nucleus, or center, of some number of protons and neutrons. The atom also has a number of electrons, which can be viewed as orbiting the nucleus. Even when atoms are combined into molecules, they move, as least by vibrating within the molecule. Many nonmetal atoms combine, by sharing electrons, into molecules, building blocks of many kinds of matter. Some nonmetal atoms, such as atoms of the "noble gases" helium and neon, can exist uncombined. When metals and nonmetals combine, gaining or losing electrons, they form solids called ionic crystals. Salt is an example. Atoms of metal elements can combine with each other into metallic solids.Atoms make up all matter. They can also cause explosions.

How would you describe the flow of electrons?

The flow of electrons "looks different" from application to application. If we look inside a cathode ray tube, the electrons look like water coming out a hose nozzle set on "direct stream" or the like. In a conductor, like a piece of wire, it's a whole other story. In that case, the electrons in the conductor support current flow by "moving over one" when one electron enters one end of a wire. An electron at each "atomic interval" or so in the wire moves over and an electron emerges from the other end of the wire. Note that the electrons ''already in the wire'' are the ones supporting current flow by moving over a "place" each time an electron enters. There are many electrons in a little bit of current, but there are many more in a given conductor like copper wire. An electron that goes in one end may not emerge from the other end for hours or days or weeks (or longer), depending on the variables involved.
