Orbitals and Electron Configuration
- The orbital shape that can hold the most electrons is the s orbital, which can hold a maximum of 2 electrons.
- The energy level that can hold the most electrons is the third energy level, which can hold a maximum of 18 electrons.
Electron Configuration
- Elements in group 12 have an electron configuration that ends in d10.
- A fluorine atom has an electron configuration of 1s² 2s² 2p⁵.
- A cerium atom has a total of 58 electrons.
- An iron atom has an electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁶ 4s².
Valence Electrons
- Elements in group 1 have 1 valence electron.
- Elements in group 17 have 7 valence electrons.
- Valence electrons are the outermost electrons of an atom that participate in chemical bonding.
- The number and arrangement of valence electrons determine the chemical properties of an element.
Energy Levels
- The energy level of an electron is notated using the format n, where n is the energy level number.
Orbital Shape
- The shape of an orbital is not always spherical.
