Chapter 2, Problem 51QAP

Interpretation Introduction

Interpretation:

The empty spaces in the table depicting the nuclear symbol, charge, number of protons, neutrons and electrons need to be filled appropriately

Concept Introduction:

• Every system found in nature is a composite of atoms, molecules, ions or other particles
• These are composed of fundamental subatomic particles: protons, neutrons and electrons.
• An atom is represented by a specific notation which is represented as: $\text{E}$
• Here: E = chemical representation/formula of a particular element

Each atom is characterized by two quantities: Atomic number (Z) and atomic mass (A) Z = atomic number = number of protons = number of electrons ------ (1)

A = atomic mass = number of protons + number of neutrons ------ (2)

• For an ion: number of electrons = number of protons + charge on the ion ------ (3)
