What is called the middle of the periodic table?

What is called the middle of the periodic table?

In the periodic table of elements, there are seven horizontal rows of elements called periods. The transition metalsmake up the middle block of the periodic table. The transition elements or transition metals occupy the short columns in the center of the periodic table, between Group 2A and Group 3A.

What are the names of the elements in the middle of the table?

First Line: Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, Zinc. Second Line: Yttrium, Zirconium, Niobium, Molybdenum, Technetium, Ruthenium, Rhodium, Palladium, Silver, Cadmium. Third Line: Hafnium, Tantalum, Tungsten, Rhenium, Osmium, Iridium, Platinum, Gold, Mercury.

What is Group 7 called?

the halogens
The Group 7 elements are called the halogens. They are placed in the vertical column, second from the right, in the periodic table . Chlorine, bromine and iodine are the three common Group 7 elements.

What is the name of the 4th halogen?

The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).

What type of element is hafnium?

metal
hafnium (Hf), chemical element (atomic number 72), metal of Group 4 (IVb) of the periodic table. It is a ductile metal with a brilliant silvery lustre.

What is Group 1 called?

alkali metal
alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).

What is the name of group 8A in periodic table?

Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.

What is Group 6A called?

Group 6A (or VIA) of the periodic table are the chalcogens: the nonmetals oxygen (O), sulfur (S), and selenium (Se), the metalloid tellurium (Te), and the metal polonium (Po). The name “chalcogen” means “ore former,” derived from the Greek words chalcos (“ore”) and -gen (“formation”).

Why are Group 17 called halogens?

The group 17 elements include fluorine(F), chlorine(Cl), bromine(Br), iodine(I) and astatine(At) from the top to the bottom. They are called “halogens” because they give salts when they react with metals.

What is element 72 on the periodic table?

The element is number 72 in the periodic table, and is called hafnium. It takes its name from hafnium, the old Latin name for Copenhagen which is the city in which it was first isolated in 1922.

What are the elements in the middle of the periodic table?

What are the elements in the middle of the periodic table? Group (s) 3-12 are the Transition Metals. First Line: Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, Zinc. Second Line: Yttrium, Zirconium, Niobium, Molybdenum, Technetium, Ruthenium, Rhodium, Palladium, Silver, Cadmium.

What are the rows and columns of the periodic table called?

The seven rows of the table, called periods, generally have metals on the left and non-metals on the right. The columns, called groups, contain elements with similar chemical behaviours.

Where are transition elements found on the periodic table?

The transition elements or transition metals occupy the short columns in the center of the periodic table, between Group 2A and Group 3A.
