What is the difference between A group and B group In periodic table?
In group A elements, the added electrons goes to the outermost shell. In group B, the additional electron goes to penultimate shell. For example, in group III A, the added or increased electron occupies outermost shell. The number of valence electrons increases.
What is A and B In modern periodic table?
Calcium (Ca) is in group 2, for it contains two valence electrons. In the old IUPAC system the letters A and B were designated to the left (A) and right (B) part of the table, while in the CAS system the letters A and B are designated to main group elements (A) and transition elements (B).
What are the 18 groups of the periodic table?
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 A and group B in periodic table?
Elements are arranged by reactivity in the periodic table. The columns with B (IB through VIIIB) are called the transition elements. The columns with A (IA through VIIIA) are called the main group elements. The elements can also be divided into two main groups, the metals and the non-metals.
What is group 5 on the periodic table called?
Group 5A (or VA) of the periodic table are the pnictogens: the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metal bismuth (Bi).
What is group A and group B in the periodic table?
The elements in group IA are called the alkali metals. The metals in group IB (copper, silver and gold) are sometimes called the coinage metals. The columns with B (IB through VIIIB) are called the transition elements. The columns with A (IA through VIIIA) are called the main group elements.
Is modern periodic table complete?
Scientists have confirmed the discovery of 4 new elements, which will fill in the missing elements from the periodic table’s seventh row. In 2012, the JWP began evaluating the evidence surrounding the discovery of elements 113, 115, 117, and 118. …
What is Group 13 on the periodic table called?
Boron group element, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh).
What family is Group 18?
The noble gases
The noble gases (Group 18) are located in the far right of the periodic table and were previously referred to as the “inert gases” due to the fact that their filled valence shells (octets) make them extremely nonreactive. The noble gases were characterized relatively late compared to other element groups.
