All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties. Understanding these trends is done by analyzing the elements electron configuration; all elements prefer an octet formation and will gain or lose electrons to form that stable configuration.

Some elements are called metalloids because they are in between metals and non-metals, and you can see that the metalloids are also in between the metals and non-metals in the periodic table. The most reactive elements are on the edges of the table (groups 1 and 17), and the most reactive non-metals are O and F, in the top right corner.

Ionization energy is always positive. The ionization energy of the elements within a period generally increases from left to right. This is due to valence shell stability. The ionization energy of the elements within a group generally decreases from top to bottom. This is due to increasing electron energy shell. The noble gases possess very high ionization energies because of their full valen

Key examples include silicon, important in electronics; boron, used in heat-resistant glass; arsenic, known for toxicity and reduced use in pesticides; and antimony, which strengthens lead mixtures and is vital for electronic applications. The unique characteristics of metalloids allow them to fulfill diverse roles across various industries.
