Periodic Table - Groups and Periods

Front

What is the Periodic Table?

Back

A tabular arrangement of chemical elements, organized by increasing atomic number, which shows periodic trends in properties.

Front

What are groups in the Periodic Table?

Back

Vertical columns in the Periodic Table that contain elements with similar chemical properties and the same number of valence electrons.

Front

What are periods in the Periodic Table?

Back

Horizontal rows in the Periodic Table that indicate the number of energy shells an atom has.

Front

What is reactivity in terms of elements?

Back

Reactivity refers to how readily an element combines with other substances, often influenced by its electron configuration.

Front

Which group contains the most reactive metals?

Back

Group 1, known as the Alkali Metals, contains the most reactive metals.

Front

What is the significance of valence electrons?

Back

Valence electrons determine an element's chemical properties and its ability to bond with other elements.

Front

What is the difference between metals, non-metals, and metalloids?

Back

Metals are typically shiny, conductive, and malleable; non-metals are dull, insulative, and brittle; metalloids have properties of both.

Front

What element is in Group 2, Period 6?

Back

Barium (Ba) is in Group 2, Period 6.

Front

What is the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is the role of the atomic mass in the Periodic Table?

Back

Atomic mass indicates the average mass of an element's isotopes, reflecting the number of protons and neutrons.
