Periodic Table Flashcard

Front

What are noble gases?

Back

Noble gases are the elements in Group 8A of the periodic table, known for their lack of reactivity due to having a full valence shell. Examples include helium, neon, and argon.

What is true about all elements in Group 18?

Back

All elements in Group 18 (noble gases) are gases at room temperature.

Front

What are transition metals?

Back

Transition metals are the elements found in groups 3B to 12B of the periodic table, characterized by their ability to form variable oxidation states and colored compounds. Examples include iron, copper, and gold.

Front

What are alkali metals?

Back

Alkali metals are the elements in Group 1A of the periodic table, known for being highly reactive and having one valence electron. Examples include lithium, sodium, and potassium.

Front

What are rare earth metals?

Back

Rare earth metals refer to the lanthanide series of elements, which are known for their similar properties and are often used in high-tech applications.

Front

What is the significance of valence electrons?

Back

Valence electrons are the outermost electrons of an atom and determine how an element reacts chemically with other elements.

Front

What are halogens?

Back

Halogens are the elements in Group 17 of the periodic table, known for being highly reactive nonmetals. Examples include fluorine, chlorine, and iodine.

Front

What is the periodic table?

Back

The periodic table is a tabular arrangement of chemical elements, organized by increasing atomic number, which displays periodic trends in properties.

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 are metalloids?

Back

Metalloids are elements that have properties intermediate between metals and nonmetals. Examples include silicon and germanium.
