Ions and Isotopes Flashcard Review

Front

What is an ion?

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

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 an isotope?

Back

Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons.

Front

How do you determine the number of protons in an atom?

Back

The number of protons in an atom is equal to its atomic number, which is unique to each element.

Front

How do you determine the number of electrons in a neutral atom?

Back

In a neutral atom, the number of electrons is equal to the number of protons.

Front

What is the significance of the atomic mass?

Back

The atomic mass is the weighted average mass of an element's isotopes, reflecting both the mass and the relative abundance of each isotope.

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, following the law of conservation of mass.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a chemical reaction where one element replaces another in a compound.
