Hydrogen Atomic Structure and Isotopes

This video tutorial explains how to determine the protons, neutrons, electrons, and mass number for hydrogen. It covers the atomic number, neutrality, and isotopes of hydrogen, including stable and unstable forms. The video also discusses the relationship between mass number and atomic mass on the periodic table. Viewers are encouraged to visualize these concepts and complete a practice table to reinforce learning.

What is the main focus of this video tutorial?

• Understanding the periodic table

• Learning about hydrogen's atomic structure

• Exploring chemical reactions

• Studying the history of hydrogen

What determines the atomic number of an element?

• Number of protons

• Mass number

• Number of electrons

In its most common form, how many neutrons does hydrogen have?

• Two

• Three

• One

• Zero

What is the mass number of the most common form of hydrogen?

• Four

• One

• Three

• Two

What is an isotope of hydrogen with one neutron called?

• Hydrogen-1

• Hydrogen-2

• Hydrogen-3

• Hydrogen-4

Which isotope of hydrogen is known to be radioactive?

• Hydrogen-2

• Hydrogen-1

• Hydrogen-3

• Hydrogen-4

Why are hydrogen isotopes with more than two neutrons not found in nature?

• They are too light

• They are too unstable

• They are too common

• They are too stable

How is the atomic mass on the periodic table determined?

• By the number of neutrons

• By the number of protons

• By a weighted average of isotopes

• By the number of electrons

Why is the atomic mass of hydrogen a decimal number?

• Because it is an average of isotopes

• Because it is a stable element

• Because it has no neutrons

• Because it is a whole number
