Transition metals refer to the 38 elements from groups three to 12 on the periodic table. They are hard, ductile, malleable and capable of conducting heat and electricity. They often have several common oxidation states, because their valence electrons exist in more than one shell.Know More
The five d orbitals become more filled, starting from left to right on the periodic table. The loosely bound d electrons contribute to the high malleability and electrical conductivity of the elements.
Transition elements have low ionization energies. They have a wide range of positively charged forms or oxidation states. Positive oxidation states enable these metals to create numerous different ionic and partially ionic compounds. The d orbitals separate into two energy sublevels due to the formation of complexes. This allows most of the complexes to absorb particular frequencies of light, forming characteristic colored compounds and solutions.
Three noteworthy transition elements are iron, nickel and cobalt, which are the only elements that produce a magnetic field. Generally, these metals have high melting and boiling points. Moreover, they typically form colored compounds. Another property of transition metals is that they are often paramagnetic.
The most abundant transition elements are iron and titanium. Important transition metals include silver, copper and iron. Many of these elements serve as catalysts for industrial reactions.Learn more about Chemistry
The elements of the periodic table in groups 1A to 8A are called the main-group elements. They are sometimes also called the representative elements and they are the most abundant in the universe.Full Answer >
The alkaline earth metals are a group of elements on the periodic table that contain two electrons in their outermost energy levels and exhibit similar characteristics such as high reactivity. This group of elements consists of beryllium, magnesium, calcium, strontium, barium and radium.Full Answer >
Alkali metals are highly reactive, explosive metals found in Group 1 of the periodic table. This group of elements includes sodium, potassium, rubidium, lithium, cesium and francium. While they all occur in nature, they occur in their pure forms only as salts. Each alkali metal has its own list of interesting properties.Full Answer >
Metals are shiny because metals contain free electrons that vibrate when they come in contact with light. When the electrons vibrate, they produce their own light. This is reflected back and is what creates the shiny, lustrous appearance of metal.Full Answer >
