Lucy, Ragnar, and Darbey are studying chemistry and discussing how to calculate the atomic mass of an element. What method should they use?

• Average of the masses of all naturally occurring isotopes

• Weighted average of the masses of all naturally occurring isotopes

• Sum of the masses of all naturally occurring isotopes

• Mass of the most abundant isotope

In a chemistry class, Arjun and Billy are discussing the relationship between the number of protons and the atomic number of an element. What is the correct relationship?

• The number of protons in an atom is half of the atomic number.

• The number of protons in an atom is greater than the atomic number.

• The number of protons in an atom is unrelated to the atomic number.

• The number of protons in an atom is equal to the atomic number.

• Opposite

• Equal

• Different

• Unrelated

In a chemistry class, Denali learns about isotopes and wants to explain it to Isla and Avery. How can he describe an isotope to them?

• A variant of an element with the same number of protons but a different number of electrons.

• A variant of an element with the same number of neutrons but a different number of protons.

• A variant of an element with the same number of protons but a different number of neutrons.

• A variant of an element with the same number of electrons but a different number of protons.
