Periodic Table Families

Front

What are Alkali Metals?

Back

Alkali Metals are a group of soft, silvery, and very reactive elements found in Group 1 of the periodic table. They react vigorously with water.

Front

What are the properties of Metalloids?

Back

Metalloids have properties of both metals and nonmetals. They are often semiconductors and can be shiny or dull.

Front

What is the classification of Radium (Ra)?

Back

Radium (Ra) is classified as an alkaline earth metal, found in Group 2 of the periodic table.

Front

Which group of non-metals is the most reactive?

Back

The Halogens are the most reactive group of non-metals, found in Group 17 of the periodic table.

Front

What are Nonmetals?

Back

Nonmetals are elements that are typically dull, brittle solids or gases, insulators, poor conductors of heat and electricity, and have low melting points.

Front

What is the general reactivity trend of Alkali Metals?

Back

Alkali Metals become more reactive as you move down the group in the periodic table.

Front

What are the main characteristics of Alkaline Earth Metals?

Back

Alkaline Earth Metals are shiny, silvery-white, and somewhat reactive, but less so than Alkali Metals. They are found in Group 2.

Front

What distinguishes Halogens from other non-metals?

Back

Halogens are highly reactive non-metals that readily form salts with metals and are found in Group 17.

Front

What is the significance of the periodic table's groups?

Back

The groups in the periodic table indicate elements that have similar chemical properties and the same number of valence electrons.

Front

What are the common uses of Metalloids?

Back

Metalloids are commonly used in semiconductors and materials for electronics due to their intermediate electrical conductivity.
