Electrons occupy the energy levels of an atom. The energy level of an atom exists in the electron cloud that surrounds the nucleus. The nucleus is home to the protons and neutrons of the atom.Know More
Electrons are negatively charged. This negative charge balances out the positive charge of the protons in the nucleus of the atom.
Electrons move at a high speed, making it hard to pinpoint their exact location. The electrons are organized in shells at a specific distance away from the nucleus.
The higher the atomic number of an element is, the more electrons it has; therefore, those with higher atomic numbers have more shells and are larger.Learn more about Atoms & Molecules
The first ionization energy generally decreases down a group due to the increasing distance of the valence electrons from the nucleus of an atom. The increasing gap lowers the attractive force of the protons that pull the electrons closer to the nucleus.Full Answer >
The third energy level of an atom, referred to as the M shell, can hold a maximum of 18 electrons. The number of electrons that any particular element has in the third level depends on its location on the periodic table and can range from none to 18 electrons.Full Answer >
There is a potential maximum of 50 electrons in the fifth energy level of an atom. The formula for determining the maximum number of electrons in any energy level is two times n squared, where n is the energy level.Full Answer >
The highest occupied level is the outermost level of the atom that contains electrons. Atoms have several levels much like a house, and each level of the atom fills with electrons level by level starting at the lowest. The first level of the atom fills up first. Then, the second level fills up and so forth. Not every atom has all of its levels occupied by electrons. For some atoms, the highest occupied level is the first level, while for others it is the third level.Full Answer >
