Front

What are noble gases?

Back

Noble gases are a group of elements in Group 18 of the periodic table that are known for their lack of reactivity due to having a full valence shell.

Front

What are alkaline earth metals?

Back

Alkaline earth metals are the elements in Group 2 of the periodic table, known for being reactive and having two valence electrons.

Front

What is the significance of valence electrons?

Back

Valence electrons determine how an element reacts chemically and are involved in the formation of bonds.

Front

What are metalloids?

Back

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

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.
