Ions & Isotopes

Front

What is an isotope?

Back

Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons, resulting in different atomic masses.

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.

Front

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

Back

To find the number of neutrons, subtract the atomic number (number of protons) from the mass number (total number of protons and neutrons).

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

How do you calculate the charge of an ion?

Back

The charge of an ion is calculated by subtracting the number of electrons from the number of protons. Charge = Protons - Electrons.

Front

What is the mass number of an atom?

Back

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

Front

What does the symbol X represent in isotopes?

Back

In isotopes, X represents the chemical symbol of the element.

Front

What is the significance of the number in the isotope notation (e.g., Carbon-12)?

Back

The number in isotope notation indicates the mass number, which is the sum of protons and neutrons.

Front

How many protons does Carbon-13 have?

Back

Carbon-13 has 6 protons.
