Your question is not entirely correct; the current model does not show electrons traveling around a nucleus, but rather, surrounding a nucleus in the form of a cloud. Traveling electrons would necessarily emit photons and lose energy, and would therefore spiral into the nucleus. The current model is quantum mechanics.
That is DC - direct current.
Original Answer:Neutrons, Protons and Electrons.New Answer:Neutrons and protons are no longer considered fundamental particles; scientists understand the properties of smaller particles that compose them. Current models describe three types of fundamental particles (quarks, leptons and bosons) of which all elements are made.
a battery always produces a direct current.the electrons always travel from the negetiove to the positive terminal.But the direction of the current is the opposite that is from the positive to the negetive terminal.
Atoms are composed of three main types of particles: protons, neutrons, and electrons. Protons have a positive electrical charge, electrons have a negative charge, and neutrons have no charge. The positive charge of the protons is balanced by the negative charge of the electrons, creating a neutral atom overall.
No, electrons and current are not the same thing. Electrons represent charge. Charge is simply a difference in free electrons between two points. Current, on the other hand, is a flow of charge, or of electrons, from one point to another. Current, in amperes, is defined as coulombs (charge of electrons) per second past a point in a circuit.

It is made up of protons, neutrons, and electrons. The protons and neutrons are found in the nucleus of the atom, while the electrons are found moving around the outside of the nucleus. This is known as the "electron cloud" since the electrons move around randomly. The most current atom model is the Quantum Mechanical Model, if this helps.
The most current model of how the atom is constructed consists of electrons in constant motion around the nucleus, like waves in a probability field. Protons and neutrons vibrate inside the nucleus and quarks vibrate inside the protons and neutrons.

To have an electrical current, you need a source of voltage (e.g., battery), a complete circuit (including conductive material), and a load (device that uses the electricity).
Electrons are the only particles in an atom that are free to move because they have a negative charge and are loosely bound to the nucleus. Protons and neutrons are tightly bound within the nucleus and do not move easily. Electrons carry electrical current in materials because of their mobility.
J.J. Thomson's model proposed the "plum pudding" model, where electrons were embedded in a positively charged sphere. The current model of the atom, based on Niels Bohr's work, describes electrons in specific energy levels or orbitals around a nucleus composed of protons and neutrons. This model incorporates quantum mechanics and has a more detailed understanding of electron behavior.
Electrons in a metal wire move freely in the presence of an electrical current, flowing in a specific direction. In the absence of an electrical current, electrons still move randomly within the wire due to thermal energy, but there is no net flow of charge.
The current view of the atom describes the location of electrons as existing in electron clouds or orbitals around the nucleus. Electrons do not follow a specific path but are rather found within a specific probability distribution around the nucleus. This model is known as the quantum mechanical model.
