Isoelectronic species have same:
Correct answer: A. Electronic configuration
- A. Electronic configuration
- B. Ionic size
- C. Reactivity
- D. pH
Explanation
Isoelectronic species are atoms, ions, or molecules that have the same number of electrons and therefore the same electronic configuration. This means that they have the same number of electrons in their valence shell, which is the outermost shell of electrons that are involved in chemical bonding. Examples of isoelectronic species include O2-, F-, and Ne, which all have the same electronic configuration as neon (1s2 2s2 2p6).

About Electronic Configuration
Electronic configuration describes how electrons occupy shells, subshells and orbitals around an atom. Questions use the Aufbau principle, Pauli exclusion principle and Hund's rule to write configurations, identify valence electrons, form ions and explain periodic trends, including common exceptions such as chromium and copper.
