What do you call the element in group 1B and 2B?
Some of these groups have special names. The elements in group IA are called the alkali metals. The elements in group IIA are called the alkaline earth 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.

What is group 1B 8B on the periodic table?
The transition elements get grouped together as the “B” elements, or groups #1B – 8B. Helium is different from all of the other elements. It can only have two electrons in its outer shell. Even though it only has two, it is still grouped with elements that have eight (inert gases).
What is Group 11 on the periodic table called?
Group 11: Transition Metals.
What is Group 12 on the periodic table called?
zinc group element, any of the four chemical elements that constitute Group 12 (IIb) of the periodic table—namely, zinc (Zn), cadmium (Cd), mercury (Hg), and copernicium (Cn).
What is 1A and 2A in periodic table?
Families: 1A – alkali metals. 2A – alkaline earth metals. 7A – halogens.
What group will have a 2+ charge?
alkali earth metals
The group that has elements with a 2 charge is alkali earth metals (group 2). Almost all the metals in the alkaline earth group can donate their two outermost electrons in order to form cations having a 2+ charge.
What is the charge of Group 12?
+2
The group 12 metals are similar in abundance to those of group 11, and they are almost always found in combination with sulfur. Group 12 metals tend have low melting and boiling points (due to the weak metallic bonding of the ns2 electrons) and charges of +2 or +1.
Why is Group 12 not a transition metal?
Transition metals are those metals who have partially filled d-orbital means not fully filled. But In group 12 elements zn,Cd and Hg have fully filled d-orbital. That’s why they are not considered as transition metals.
What are the 12 elements of the periodic table?
The elements of the periodic table sorted by atomic number
| Atomic number | Name chemical element | Symbol |
|---|---|---|
| 10 | Neon | Ne |
| 11 | Sodium | Na |
| 12 | Magnesium | Mg |
| 13 | Aluminum | Al |
Where is group 2A on the periodic table?
Groups are the vertical columns on a periodic table, and group 2A is on the left. Sometimes, group 2A is represented by roman numerals, or IIA. Alkaline earth metals include beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra).
What do groups 1A and group 2A elements have in common?
What do group 1A and group 2A elements have in common? Both very reactive, react with water, form positive ions, and all metals. Explain why fluorine reacts with all elements except helium, neon, and argon. Noble gases tend not to react with anything.
How are the elements in the periodic table numbered?
Except for VIIIB, which covers three families of elements (8, 9 and 10 of the modern numbering system), groups IB through VIIB are numbered according to their expected maximum valence. For example, elements in Gr In old-style periodic tables, there are two sets of groups numbered I through VIII (typically using Roman numerals).
Why are groups divided into subgroups on the periodic table?
The dividing of groups into subgroups was felt necessary because many elements which doesn’t have similar properties came under same group. , Interested in Theoretical and Organic chemistry. There are two commonly used formats of the periodic table. In one of them groups are numbered 1 through 18.
What are the trends in the periodic table?
Trends in the Periodic Table. (a) Valency- Combing capacity of atoms. The number of valence electrons in metals and 8 minus the number of valence electrons in non-metals. In a group- As we go down a group in the Periodic Table the number of valence electrons stay the same. While moving down a group the valency stays the same.
How are elements numbered according to their expected valence electrons?
Except for VIIIB, which covers three families of elements (8, 9 and 10 of the modern numbering system), groups IB through VIIB are numbered according to their expected maximum valence. For example, elements in Group IIIB all have 3 valence electrons, and they tend to form compounds where their oxidation state is +3.
