Metals and Non-metals MCQs

Elements are primarily classified into metals and non-metals based on their physical and chemical properties. Metals encompass s-block elements, such as alkali metals and alkaline earth metals, as well as d-block transition metals, lanthanides, and actinides. Non-metals are found on the right side of the periodic table in the p-block, including elements like halogens, noble gases, oxygen, and nitrogen. Metals are characterized by their ductility, malleability, and excellent conductivity of heat and electricity. With the exception of mercury, all metals are naturally found in the solid state.
