What is an electron configuration quizlet?

electron configuration. the arrangement of electrons in the energy levels, sublevels and orbitals of atoms. s orbitals. spherical orbitals; first to be filled for any energy level; can only hold 2 electrons.

What is an electron configuration give an example quizlet?

The information given in an atom’s electron configuration includes energy level numbers, sub level letters, and superscripts that represent the number of electrons in each sub-level. Examples: Nitrogen = 1s^2, 2s^2, 2p^3.

Which of the following is the best definition of electronic configuration?

Electronic configuration is the arrangement of electrons around the nucleus of a particular atom or molecule.

What is the Aufbau principle quizlet?

Aufbau principle. States that each electron occupies the lowest energy orbital available. Electron configuration. The arrangement of electrons in an atom, which is prescribed by three rules- the aufbau principle, the Pauli exclusion principle, and hund’s rule.

What is the electron configuration for P quizlet?

The electron configuration of phosphorus is 1s^22s^22p^63s^23p^3 and it reveals that phosphorus has 5 valence electrons in the 3s and 3p orbitals.

What is electron configuration in your own words?

An electron configuration is the arrangement of electrons within an atom. The electron configuration describes where the electrons are inside orbitals. The structure of the Periodic table of elements is partly based on electron configuration.

How do you describe electron configuration?

The most common way to describe electron configurations is to write distributions in the spdf notation. Although the distributions of electrons in each orbital are not as apparent as in the diagram, the total number of electrons in each energy level is described by a superscript that follows the relating energy level.

What is the Hund’s rule in chemistry?

Hund’s Rule. Hund’s rule: every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.

What is Hund’s rule quizlet?

Hund’s rule states that, orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron and that each of the single electrons must have the same spin.

What three principles guide the electron configuration of an atom quizlet?

Three rules—the aufbau principle, the Pauli exclusion principle, and Hund’s rule—tell you how to find the electron configurations of atoms.

How do you remember electronic configuration?

1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, 8s. Although this looks confusing, there is an easy way to remember. Go in order of the lines from top to bottom, top right end to bottom left of each line.
