What does the term electron orbital describe? an electron orbital describes the orbit of an electron around the nucleus. an electron orbital describes a three-dimensional space where an electron can be found 90% of the time. an electron orbital describes the exact distance of an electron from the nucleus.

The correct answer is B. An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.

Explanation:

Electrons are negatively charged particles found in atoms. These different from protons and neutrons are not located in the nucleus of the atom but orbit it. Additionally, electrons do not orbit the nucleus following a linear pattern but they have a wave-like behavior which means they move in a three-dimensional space or area known as electron orbital in which they can be found most of the time, this space of area is determined depending on energy, momentum, and other factors. Thus, an electron orbital is "a three-dimensional space where an electron can be found 90% of the time".

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
