Electron Configuration and Orbitals

________ follow the filling of 4s by filling 3d in the 4th period.

________: the most stable organization is the lowest possible energy.

________, l: values are integers from 0 to (n- 1); defines the shape of the orbitals.

________: for a set of orbitals in the same sublevel, there must be one electron in each orbital before pairing and the electrons have the same spin, as much as possible.

An orbital can hold a maximum of two electrons and they must have ________.

Each ________ consists of: a number denoting the energy level; a letter denoting the type of orbital; a superscript denoting the number of electrons in those orbitals.

________: describes a spatial distribution of electron density; a(n) ________ is described by a set of three quantum numbers.

Every ________ in an atom has a unique set of quantum numbers.

________, n: describes the energy level of an electron in an atom; values of n range from n= 1 (ground state) to n= infinity (the electron has separated from the atom)

________ represent the electrons.

When filling ________ the lowest energy is attained when the number of electrons having the same spin is maximized.

________ can be grouped into shells, subshells and orbitals.

________ (atomic numbers 57 to 70): have electrons entering the 4f sublevel.

________: the way electrons are distributed in an atom.

describes a spatial distribution of electron density; an orbital is described by a set of three quantum numbers

n, l, ml and ms

describes the energy level of an electron in an atom; values of n range from n=1 (ground state) to n=infinity (the electron has separated from the atom)

values are integers from 0 to (n-1); defines the shape of the orbitals

the "spin" of an electron describes its magnetic field, which affects its energy; the spin quantum number has only two allowed values, +1⁄2 and -1⁄2
