The elements of group 18 are known as inert because they havecompletelyfilled atomic orbitals.
Potassium would strongly react with the elements in group 17 and group 16.
Alkali Earth metals are the most reactive metals on the periodic table.
Noble gases or group 18 elements
Group-18 elements do not react. They are noble gases.They are inert in nature.Noble gases are unlikely to react. They are in the 18th period of the periodic table. They are called inert gasses too.
A group in Periodic Table is the column of element in periodic table
Group 8 on the periodic table is referred to as the Noble gases because they all have complete electron shells meaning it is very unlikely for them to react with other substances.
Very reactive metals - from group 1 and 2 of the periodic table - can react with water.
Potassium is a metal, and it would react to group 17 (7A) because those elements are nonmetals.
The periodic table tells you that elements in the same group have similar chemical properties because they have the same number of valence electrons. This influences how they react with other elements and helps predict their behavior in compounds.
Lead is in the group 14 of the Periodic Table.
Chlorine is in Group 17 of the Periodic Table.
Astatine is placed in group-17 in the Periodic Table. Its symbol is At.
