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.

What charge will an element with 3 valence electrons likely form on its ion?

Back

+3

Front

What is the ionic symbol for Krypton?

Back

Kr (Krypton is a noble gas and does not typically form ions).

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.

What charge does a beryllium ion have?

Back

+2

Front

How do you determine the charge of a simple ion?

Back

The charge of a simple ion can be determined by the number of valence electrons: metals typically lose electrons and become cations, while nonmetals gain electrons and become anions.

Front

What is the significance of valence electrons in ion formation?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming bonds and ions. The number of valence electrons determines whether an atom will lose or gain electrons.
