Chapter 1: Number Of Protons - Nuclear Chemistry Flashcards

Vocabulary flashcards covering medical applications, stability thresholds based on atomic numbers, and particle notations from Chapter 1.

PET Scan

Acronym for positron emission tomography; a diagnostic tool in radioactive nuclear medicine that allows physicians to see inside the body without making an incision.

Atomic Number $83$ Threshold

The stability demarcation where elements with atomic number $83$ and less tend to be non-radioactive, whereas elements with atomic numbers greater than $83$ are unstable.

Mass Number

In nuclear particle notation, the top number representing the total count of protons and neutrons added together.

Proton Count Notation

In nuclear particle notation, the lower number representing the number of protons alone.

Alpha Particle

A type of nuclear particle commonly designated by the symbol with the alpha letter from the Greek alphabet or its corresponding chemical notation.

Beta Particle

A type of nuclear particle that is essentially a high energy electron.
