Electrons are negatively charged particles that orbit the nucleus of an atom, while protons are positively charged particles that make up the nucleus. Electrons are much smaller in size and mass compared to protons.
Electrons move in specific energy levels or orbitals around the nucleus of an atom. These energy levels determine the distance of the electron from the nucleus and its energy state. Electrons can also move between energy levels by absorbing or releasing energy.
Yes, electrons can move from one atom to another through a process called electron transfer. This typically happens during chemical reactions when atoms share, gain, or lose electrons to form new compounds.
Electrons play a crucial role in the flow of electricity. When electrons move from one atom to another, they create an electric current. This movement of electrons is what powers electrical devices and circuits.
No, electrons can move in either direction within an atom, depending on the circumstances. In terms of electricity, electrons typically move from the negative terminal to the positive terminal, but they can also flow in the opposite direction under certain conditions.
