Periodic Table Trends

Front

What are the main groups of elements in the periodic table?

Back

The main groups are Metals, Nonmetals, Metalloids, Noble Gases, Alkali Metals, and Halogens.

Front

What are Noble Gases?

Back

Noble Gases are elements in Group 18 of the periodic table that are colorless, odorless, and inert under standard conditions.

Front

What are Metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals and are found along the zigzag line on the periodic table.

Front

What is the significance of valence electrons?

Back

Valence electrons determine how an element reacts chemically with other elements.

Front

Which group contains elements with 1 valence electron?

Back

Group 1, known as the Alkali Metals, contains elements with 1 valence electron.

Front

What is the periodic trend for atomic size?

Back

Atomic size increases down a group and decreases across a period from left to right.

Front

What are Halogens?

Back

Halogens are elements in Group 17 of the periodic table known for being highly reactive nonmetals.

Front

What is the difference between metals and nonmetals?

Back

Metals are typically shiny, conductive, and malleable, while nonmetals are dull, insulative, and brittle.

Front

What is the role of the zigzag line in the periodic table?

Back

The zigzag line separates metals from nonmetals and indicates the location of metalloids.

Front

How do chemical properties change across a period?

Back

Chemical properties change as you move across a period due to changes in electronegativity and ionization energy.
