Properties of Elements & Families (Obj 4-2)

Front

What are noble gases?

Back

Noble gases are a group of chemical elements in Group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell of electrons. Examples include helium, neon, and argon.

Front

What color on the periodic table corresponds with noble gases?

Back

Black.

Front

What is a physical change?

Back

A physical change is a change that affects one or more physical properties of a substance without altering its chemical composition. An example is boiling water.

Front

What is the primary type of element found in the periodic table?

Back

Metals.

Front

What are the general properties of metals?

Back

Metals are typically shiny, malleable, ductile, and good conductors of heat and electricity.

Front

Which property is NOT characteristic of metals?

Back

Non-conductors.

Front

What color on the periodic table corresponds with halogens?

Back

Red.

Front

What are halogens?

Back

Halogens are a group of elements in Group 17 of the periodic table, known for their reactivity and tendency to form salts with metals. Examples include fluorine, chlorine, and bromine.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties, allowing for the prediction of element behavior.

Front

What are metalloids?

Back

Metalloids are elements that have properties intermediate between metals and nonmetals. They are found along the zig-zag line on the periodic table.
