Question
Chapter 2, Problem 115AP
Interpretation Introduction
Interpretation:
The element, from the given number of electrons and protons, is to be identified.
Concept introduction:
An anion is formed when a neutral atom gains electron(s) and acation is formed when a neutral atom loses electron(s).
The number of the protons and electrons in a neutral atom is equal to its
The number of electrons in an anion is the sum of its atomic number and the magnitude of charge on the anion, while the number of electrons in a cation is the difference between its atomic number and the magnitude of charge.
