What is groups in the periodic table called?

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.

What is Group 3 on the periodic table known as?

Group 3 is the first group of transition metals in the periodic table. The group is also called the scandium group or scandium family after its lightest member.

Which group on the periodic table are called noble gases?

noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

What is Group 2 called?

alkaline-earth metal, any of the six chemical elements that comprise Group 2 (IIa) of the periodic table. The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

What is Group 4 called in the periodic table?

titanium group
Group 4 is the second group of transition metals in the periodic table. It contains the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). The group is also called the titanium group or titanium family after its lightest member.

What is Group 2 called in the periodic table?

Alkaline Earth Metals
Group 2A — The Alkaline Earth Metals. Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

Why are Group 18 elements called noble gases?

The group 18 elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These elements are non-reactive and are called noble gases as they have their outermost orbit complete. Due to stable electronic configuration they hardly react with other elements.

Why is group 0 called inert gas?

(1) In the atoms of the inert gas elements (zero group elements), all the electronic shells, including the outermost shell, are completely filled. (2) The electronic configuration is stable, and these elements do not lose or accept electrons. These elements are gases. Hence, they are called noble gases.

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”).

What is the name of Group 7A?

Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The name “halogen” means “salt former”, derived from the Greek words halo- (“salt”) and -gen (“formation”).
