Isotope Intro

Understanding the Periodic Table00:00:01

Explanation of the periodic table, defining atomic numbers (Z) and chemical symbols as the primary identifiers for elements.

Protons, Electrons, and Atomic Numbers00:02:20

Detailed breakdown of how the atomic number determines the number of protons in an atom, and how electrically neutral atoms have an equal number of electrons.

Introduction to Isotopes00:04:40

Defining isotopes as atoms with the same number of protons but a different number of neutrons, emphasizing that elements can vary in neutron count.

Calculating Mass Number and Naming Isotopes00:06:00

How to calculate the mass number (A) by summing protons and neutrons, and the three common conventions for naming isotopes (chemistry, geology, and biology styles).
