What is the charge of a 3- ion?

Back

A 3- ion has gained three electrons, resulting in a negative charge.

Front

What is the significance of group numbers in the periodic table?

Back

Group numbers indicate the number of valence electrons in the elements of that group.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals, often found along the zig-zag line on the periodic table.

Front

What is the periodic table?

Back

The periodic table is a tabular arrangement of elements organized by increasing atomic number, showing periodic trends.
