The arrangement of electrons around the nucleus is referred to as
(A) electron configuration
(B) valence electrons.
Answer (2)
The arrangement of electrons around the nucleus is known as electron configuration, which describes how electrons are organized in atomic orbitals. Valence electrons are specific to the outermost shell, but the broader term encompasses all electrons in the atom. The correct answer is (A) electron configuration. ;
The arrangement of electrons around the nucleus is called electron configuration. This concept describes how all electrons are organized in atomic orbitals, whereas valence electrons are specifically those in the outermost shell. Thus, the correct answer is (A) electron configuration.
