Guida verificata passo dopo passo1
Identify the position of Argon (Ar) on the periodic table by locating its atomic number, which is 18.
Recall that the periodic table is divided into groups (columns) numbered from 1 to 18, each representing elements with similar chemical properties.
Understand that Group 18 contains the noble gases, which are characterized by their full outer electron shells and low reactivity.
Recognize that Argon is a noble gas because it is located in Group 18, sharing properties such as being inert and having a complete valence shell.
Conclude that Argon belongs to the Noble gases group (Group 18) based on its position and chemical characteristics.
