Isotopes, Abundances, and Density Relationships ( boron )

Flashcards cover boron isotopes and their abundances, as well as how density and mass relate when changing the order of numerator/denominator.

Isotopic abundance

The fraction of natural atoms of an element that exist as a specific isotope; for boron, Abundance(B-10) + Abundance(B-11) = 1 (normalization).

Boron-10 (B-10)

An isotope of boron with mass number 10; contributes to the natural isotopic mixture.

Boron-11 (B-11)

An isotope of boron with mass number 11; contributes to the natural isotopic mixture.

Sum-to-one constraint

Normalization condition that the total isotopic abundances add up to 1 (100%).

Density (ρ)

Mass per unit volume; ρ = m/V.

Mass (m)

The amount of matter in an object.

Mass over density

Volume; m/ρ = V.

Density over mass

Inverse volume; ρ/m = 1/V.
