Niels Bohr
an electron is found in shells , it is a subatomic particle
Electron shells fill in the order 2, 8, 18, 18, 32, 32
The layers of electrons surrounding the nucleus of an atom are called electron shells or energy levels. These shells represent the different energy levels at which electrons can orbit around the nucleus. Each shell can hold a specific number of electrons based on its capacity.
Uranium (any isotope) has 7 electron shells.
The spheres surrounding the nucleus of an atom are called protons and neutrons, protons hold the electrons in orbit around the nucleus because a proton has a positive charge which attracts the electron which has a negative charge causing electromagnetic force which holds the electron in orbit. The neutron determines the isotope of the atom but has a neutral charge.
Electrons orbit the nucleus of an atom. They move in specific energy levels called electron shells. The nucleus contains protons and neutrons.
"electron"
A group of electrons orbiting at roughly the same distance from the nucleus is called an electron shell or energy level. These shells represent different energy levels in which electrons can orbit around the nucleus of an atom.
Electrons orbit the atom's nucleus in specific energy levels, also known as electron shells or orbitals. The electrons are arranged in these levels based on their energy and distance from the nucleus.
A shell surrounding the nucleus of an atom containing electrons.
The layers of electrons surrounding the nucleus of an atom are called electron shells or energy levels. These shells are designated by the numbers 1, 2, 3, and so on, with each shell able to hold a specific maximum number of electrons.
