The hardest element is chromium, which is in group 6.
The hardest element is chromium, which is in group 6.
Group 14 of the periodic table contains one semi-metal and four metals. The semi-metal in this group is silicon (Si), while the metals include tin (Sn), lead (Pb), germanium (Ge), and flerovium (Fl). This group is known for its diverse properties, with silicon being widely used in electronics and the metals having various industrial applications.
The hardest and densest metals are typically found in the d-block of the periodic table, which contains transition metals. Elements such as tungsten, osmium, and iridium, known for their hardness and density, are located in this block. These metals exhibit unique properties due to their electron configuration and metallic bonding characteristics. In contrast, s-block and p-block metals generally have lower densities and hardness compared to those in the d-block.
sodium(Na) belongs to the Ist group. This group is also known as alkaline metals.
The group I metals (Lithium, Sodium, Potassium, etc.) are very well known for their extreme reactivity. These metals will tarnish quickly in air and can cause small detonations when thrown into water via a highly exothermic reaction that produces flammable hydrogen gas.
The hardest element is chromium, which is in group 6.
Group 3-12 contains transition metals, which are elements that have partially filled d or f electron shells. These metals have characteristic properties such as high melting points, ductility, and the ability to form colored compounds. Some commonly known transition metals in this group include iron, copper, and zinc.
Group IA or group 1 elements are known as alkali metals.

The group of alkaline earth metals consists of beryllium, magnesium, calcium, strontium, barium, and radium. They are located in group 2 of the periodic table and have similar chemical properties, such as being shiny, silvery-white, and relatively reactive. They are known for their low densities and reactivity with water.
Sodium belongs to the group 1 of the periodic table, known as the alkali metals group.
Iron is in group 8 (VIII), which is also known as the transition metals group or group 8 of the periodic table.
sodium(Na) belongs to the Ist group. This group is also known as alkaline metals.
