Hydrogen Isotopes and Nuclear Notation

The video tutorial explains isotopes, focusing on the differences in neutrons among isotopes of the same element. It uses carbon and hydrogen as examples, highlighting the unique characteristics of hydrogen isotopes, such as protium, deuterium, and tritium. The tutorial also covers the notation of isotopes and discusses how hydrogen isotopes have distinct properties compared to other elements.

What is the primary factor that differentiates isotopes of the same element?

• Atomic number

• Number of neutrons

• Number of electrons

• Number of protons

How is the mass number of an isotope determined?

• By multiplying the number of protons and neutrons

• By subtracting the number of electrons from protons

• By adding the number of protons and neutrons

• By adding the number of protons and electrons

Which of the following is NOT a name for a hydrogen isotope?

• Protium

• Deuterium

• Helium

• Tritium

What is the atomic number of hydrogen?

• 4

• 3

• 2

• 1

In hyphen notation, what does the number after the element symbol represent?

• Atomic number

• Mass number

• Number of electrons

• Number of isotopes

What does the bottom number in nuclear notation represent?

• Number of electrons

• Atomic number

• Number of neutrons

• Mass number

Which hydrogen isotope is most abundant in the universe?

• Deuterium

• Helium

• Protium

• Tritium

How does the addition of a neutron affect the mass of a hydrogen isotope?

• It does not affect the mass

• It triples the mass

• It doubles the mass

• It halves the mass

Which hydrogen isotope has no neutrons?

• Helium

• Tritium

• Deuterium

• Protium

Why do most isotopes, other than hydrogen, have similar chemical properties?

• They have the same number of protons

• They have the same number of electrons

• They have similar mass numbers

• They have similar neutron numbers
