What are inner transition metals?

Back

Inner transition metals are elements that include the lanthanides and actinides, found in the two rows at the bottom of the periodic table. They are known for their complex electron configurations.

Front

What group of elements has 3 valence electrons?

Back

The boron group (Group 13) has 3 valence electrons. This group includes elements like boron, aluminum, and gallium.

Front

What are alkaline earth metals?

Back

Alkaline earth metals are the elements in Group 2 of the periodic table, including beryllium, magnesium, calcium, strontium, barium, and radium. They are known for being reactive and forming basic oxides.

Front

What are noble gases?

Back

Noble gases are the elements in Group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell. They include helium, neon, argon, krypton, xenon, and radon.

Front

What are metalloids?

Back

Metalloids are elements that have properties intermediate between metals and nonmetals. They are typically semiconductors and include elements like silicon, germanium, and arsenic.

Front

What are alkali metals?

Back

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

Front

What are transition elements?

Back

Transition elements are the metallic elements found in Groups 3 to 12 of the periodic table. They are characterized by their ability to form variable oxidation states and colored compounds.

Front

What is the significance of valence electrons?

Back

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

Front

What are lanthanides?

Back

Lanthanides are a series of 15 elements from lanthanum (La) to lutetium (Lu) in the periodic table, known for their similar properties and use in various high-tech applications.
