Where are metals located on the periodic table?
Where are metals located on the periodic table? Metals on the periodic table are located on the left side and the center: all of groups 1 to 12, plus the lower left part of groups 13 to 16, and the lanthanides and actinides in the two rows beneath the main table.
The alkali metals (group 1) and alkaline earth metals (group 2) are on the far left, the transition metals such as iron, copper and gold fill the middle block (groups 3 to 12), and post-transition metals such as aluminium, tin and lead sit to the right of them. A stair-step line running from boron to astatine separates metals on its lower left from nonmetals on its upper right, with metalloids along it. From alchemy to plutonium and uranium, the labeled periodic table records how the history of the elements unfolded.
Hydrogen is placed in group 1 but is a nonmetal. About 92 of the 118 elements are metals, and they are mostly solid, shiny, malleable and good conductors of heat and electricity; mercury is the only metal that is liquid at room temperature, while gallium and cesium melt just above it. For a different question, see “what are elements”.
Where metals sit also explains their properties. The elements on the left have few valence electrons and lose them easily, so they form positive ions and conduct electricity through a sea of free electrons. Another common question on this site is “what is a period in the periodic table”.
Reactivity increases down the alkali metals, so cesium reacts more violently with water than lithium, while the transition metals in the middle are denser, harder and less reactive. The post-transition metals such as aluminium, gallium, tin and lead are softer and have lower melting points. If you are studying, you may also want the answer to “where are the metalloids located in the periodic table”.
Many everyday objects use metals from different regions: iron and nickel from the d-block in steel, aluminium from group 13 in cans and aircraft, and copper from group 11 in wiring. The lanthanides, such as neodymium, are called rare earth elements and are used in magnets and electronics. Nonmetals sit on the right side, and metallic character is strongest toward the bottom left, where the most reactive metals are found.
