FLASHCARD QUESTION

Front

What is an isotope?

Back

An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons, resulting in a different atomic mass.

2.

FLASHCARD QUESTION

Front

How do you determine the number of neutrons in an isotope?

Back

To find the number of neutrons in an isotope, subtract the atomic number (number of protons) from the atomic mass.

3.

FLASHCARD QUESTION

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

What is the difference between a cation and an anion?

Back

A cation is a positively charged ion (lost electrons), while an anion is a negatively charged ion (gained electrons).

6.

FLASHCARD QUESTION

Front

What does it mean for an atom to be neutral?

Back

A neutral atom has an equal number of protons and electrons, resulting in no overall charge.

7.

FLASHCARD QUESTION

Front

How does the charge of an ion relate to the number of protons and electrons?

Back

The charge of an ion is determined by the difference between the number of protons and electrons; if protons exceed electrons, the ion is positive, and if electrons exceed protons, it is negative.
