Abstract

Kimya ve Fizik alanında atomların büyüklüğünü ifade etmek için birkaç atom yarıçapı kavramı önerilmiştir. Bu çalışmada, atomik yarıçap tanımları incelenmiş, olasılık ölçüsüne dayanan ve en dıştaki elektronun hidrojen benzeri bir atomun çekirdeği ile merkezlenmiş küresel bir hacimde olma olasılığını dikkate alan olasılıksal bir atomik yarıçap kavramını sunulmuştur. Bu olasılık ölçüsüne bağlı olarak, temel durum hidrojen atomu için %99 olasılık ile atomik yarıçapı hesaplanmış ve bunun hidrojen benzeri atomik sistemler için yorumlanmıştır.

A Probabilistic Atomic Radius Definition: Application to Ground State Hydrogen-Like Atoms

Abstract

Several atomic radius concepts were proposed to express size of atoms in chemistry and physics. This study briefly surveys widely used definitions of atomic radiuses and introduces a probabilistic atomic radius concept that is based on the probability measure, which considers probability of the outermost electron to be in a spherical volume that is centered by nucleus of a hydrogen-like atom. Depending on this probability measure, 99% probabilistic atomic radius is calculated for a ground state hydrogen atom and its interpretation for hydrogen-like atomic systems is discussed.
