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 the most stable arrangement and what are they called?

The arrangement of electrons within the orbitals of an atom is known as the electron configuration. The most stable arrangement is called the ground-state electron configuration. This is the configuration where all of the electrons in an atom reside in the lowest energy orbitals possible.

What is redox reaction in microbiology quizlet?

A chemical reaction involving the transfer of one or more electrons from one reactant to another; also called oxidation-reduction reaction.

What is a stable electron configuration?

Stable configuration Their valence shell is complete. They have two or eight electrons in their valence shell. They do not gain, lose or share electrons.

Which of the following elements have a stable electron configuration?

Group 18 elements (helium, neon, and argon are shown in Figure 2) have a full outer, or valence, shell. A full valence shell is the most stable electron configuration.

What is meant by the electron configuration of an atom?

electronic configuration, also called electronic structure, the arrangement of electrons in energy levels around an atomic nucleus. According to the older shell atomic model, electrons occupy several levels from the first shell nearest the nucleus, K, through the seventh shell, Q, farthest from the nucleus.

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.

What are stable electron configurations likely to contain?

Answer and Explanation: Stable electron configurations are likely to contain: a. filled energy sublevels. Stable atoms have complete valence shells with completely filled energy sublevels.

What are redox reactions in biology?

Biology definition: Redox reaction is a chemical reaction involving both reduction and oxidation, which results in changes in the oxidation numbers of atoms included in the reaction. Oxidation is when there is an increase in oxidation number; reduction is when there is a decrease in oxidation number.

What occurs during a redox reaction quizlet?

What happens in a Oxidation-Reduction (Redox) Reaction? Electrons are transferred from one reactant to another and the oxidation states/oxidation number of certain atoms are changed.

Which of the following groups has a stable electron configuration?

Stable Electron Configuration: All of the elements in group 18, also known as the noble gases, have stable electron configuration because they reach the maximum number of electrons in their shells.
