Isotopes and Ion

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 mass number.

Front

What is the mass number of an isotope?

Back

The mass number is the total number of protons and neutrons in the nucleus of an atom.

Front

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

Back

Subtract the atomic number (number of protons) from the mass number.

Front

What is the charge of an ion?

Back

The charge of an ion is determined by the difference between the number of protons and electrons in an atom.

Front

What is a cation?

Back

A cation is a positively charged ion, formed when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion, formed when an atom gains one or more electrons.

Front

What is the significance of valence electrons?

Back

Valence electrons are the outermost electrons of an atom and are important for determining how an atom will bond with other atoms.

Front

How does iodine typically form an ion?

Back

Iodine typically gains one electron to achieve a full outer shell, resulting in a charge of -1.

Front

What is the difference between an isotope and an ion?

Back

An isotope refers to variations of an element with different mass numbers, while an ion refers to an atom that has gained or lost electrons, resulting in a charge.

Front

What is the notation for isotopes?

Back

Isotopes are often represented by the element's name followed by the mass number, e.g., Carbon-14.
