Modern periodic table In the modern periodic table, each period starts with the strong metal (in group 1 (1 A), where the metallic property decreases by increasing the atomic number, till we reach the...
Non-metals The non-metals are the elements that have more than four electrons in their outermost energy levels, The non-metals are characterized by the smallest atomic sizes and the largest electronegativity.
Metals are elements that are typically: Shiny (lustrous), Good conductors of heat and electricity, Malleable (can be hammered into sheets), Ductile (can be drawn into wires), and Solid at room temperature (except mercury).
