In the periodic table, metals are generally more numerous than non-metals.
The majority of elements in the periodic table are classified as metals. Metals are typically found on the left side and the middle of the periodic table, occupying groups 1 to 12 (excluding hydrogen) as well as some elements in groups 13 to 16. Metals exhibit properties such as high electrical and thermal conductivity, luster, malleability, and ductility. Examples of metals include iron, copper, gold, and aluminum.
Non-metals, on the other hand, are found on the right side of the periodic table, primarily in groups 14 to 16, as well as group 18 (the noble gases). Non-metals generally have properties such as lower electrical and thermal conductivity, brittleness, and lack of metallic luster. Examples of non-metals include oxygen, nitrogen, carbon, and sulfur.
While there are significantly more metals than non-metals, it's important to note that the periodic table includes a diverse range of elements with varying properties, and there are also several metalloids, which possess characteristics of both metals and non-metals.
