Atomic Structure Flashcards

Front

Protons are positively charged particles located in the nucleus.

Back

Protons are one of the three main subatomic particles in an atom.

Front

Protons and neutrons determine the mass number of an atom or ion.

Back

The mass number is the sum of protons and neutrons.

Front

Argon-40 and argon-41 are isotopes.

Back

Isotopes are the same element with different masses

Front

An atom with 13 protons and 13 neutrons is the same atom, not isotopes.

Back

Stable isotopes do not change over time.

Front

The element with atomic number 3 is lithium.

Back

Lithium has 3 protons.

Front

Particles that determine the name of an element.

Back
