Root Explanation

Isoelectronic → It is formed from "iso-" (meaning equal) and "electronic" (from "electron" which comes from the Greek "ēlektron", meaning amber, referring to the particle associated with electricity). The term describes species that have the same number of electrons, hence being equal in electron count.

Memory Tip

Think of 'iso-' meaning equal, and 'electronic' relating to electrons — this helps you remember that isoelectronic refers to entities that have an equal number of electrons.
