Electrons travel in specific energy levels around the nucleus of an atom. These energy levels are known as electron shells, and electrons move within these shells in a kind of "cloud" around the nucleus.
Photons can travel through an atom without being absorbed if they do not have enough energy to interact with the electrons in the atom. However, if a photon has enough energy to match the energy levels of the electrons in the atom, it can be absorbed, causing the electron to move to a higher energy level or be ejected from the atom.
The flow of electrons from atom to atom is an electrical current.
No, but the do orbit in a certain shell.
When all electrons in an atom are in orbitals with the lowest possible energy, the atom is in its ground state. This is the most stable arrangement for the electrons in an atom.
No, electrons are not found in the nucleus of an atom. Electrons are negatively charged particles that orbit the nucleus of an atom in specific energy levels. The nucleus of an atom consists of protons and neutrons.
Electrons
The nucleus contain protons and neutrons; these particles are also composed from quarks and gluons. Shells are the location of electrons.

Photons can travel through an atom without being absorbed if they do not have enough energy to interact with the electrons in the atom. However, if a photon has enough energy to match the energy levels of the electrons in the atom, it can be absorbed, causing the electron to move to a higher energy level or be ejected from the atom.
The space outside of the nucleus of an atom where electrons reside is referred to the electron shell or an orbital. According to quantum mechanics theory, electrons do not technically travel, they just exist around the nucleus in something like a shell or a cloud.
The space around the nucleus of an atom is called the electron cloud. The electron cloud is the space in which the electrons of that atom travel. Compared to the nucleus, the electron cloud is enormous.
The Bohr model for the atom is from 1913.
Schroedinger
A nitrogen atom has seven electrons.
Repelling Force of Gravity
Yes. The nucleus contains protons and neutrons and is electrially charged. The electrons are in a "cloud" outside the nucleus.
