What is considered a main group element?
The main group elements are classified as belonging to the s- and p-blocks in the periodic table. They range from gases such as fluorine and oxygen through nonmetals (e.g., boron, phosphorus, and sulfur) and semimetals (metalloids; e.g., germanium) to very reactive metals such as sodium and potassium.
What are main group elements examples?
Specific examples of main group elements include helium, lithium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
What are the 4 main groups on the periodic table?
Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Groups are numbered 1–18 from left to right.
Where are the main group elements found?
The main group elements are those in the s and p blocks of the periodic table, as shown in Figure 8.2. 1. Figure 8.2.
Is californium a main group element?
Californium is a radioactive chemical element with the symbol Cf and atomic number 98. Californium Atomic number (Z) 98 Group group n/a Period period 7 Block f-block.
What are group 3 elements called?
Group 3A (or IIIA) of the periodic table includes the metalloid boron (B), as well as the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). Boron forms mostly covalent bonds, while the other elements in Group 3A form mostly ionic bonds.
How many main group elements are there?
The s-, p-, and d-block elements of the periodic table are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
Is RN a main group metal?
The main-group metals usually form charges that are the same as their group number: that is, the Group 1A metals such as sodium and potassium form +1 charges, the Group 2A metals such as magnesium and calcium form 2+ charges, and the Group 3A metals such as aluminum form 3+ charges.Metals, Metalloids, and Nonmetals. 4A Pb 5A Bi 6A Po 7A At 8A Rn.
Is aluminum a main group element?

What are the 5 main groups of the periodic table?
5 Element Families Alkali metals. Alkaline earth metals. Transition metals. Halogens. Noble gases.
How many groups are in the periodic table?
Groups are numbered from 1 to 18. From left to right in the periodic table, there are two groups (1 and 2) of elements in the s-block, or hydrogen block, of the periodic table; ten groups (3 through 12) in the d-block, or transition block; and six groups (13 through 18) in the p-block, or main block.
What are the 8 groups in periodic table?
The following are the 8 groups of the periodic table: Alkali metals. Alkaline earth metals. Rare earth metals. Crystallogens. Pnictogens. Chalcogens. Halogens. Noble gases.
Is barium a main group element?
The metals that occur in Groups 1, 2, and 13–15 in the periodic table are called the main-group metals. The alkaline-earth metals—beryllium, magnesium, calcium, strontium, barium, and radium—occur in Group 2 in the periodic table (Figure I. 1).
Is chlorine a main group element?
These groups contain the most naturally abundant elements, comprise 80 percent of the earth’s crust and are the most important for life. Economically the most produced chemicals are main group elements or their compounds.Group 17 (Halogens) Group 17 2 9 F 3 17 Cl 4 35 Br 5 53 I.
Is osmium a main group element?
It is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Osmium is the densest naturally occurring element. Osmium Group group 8 Period period 6 Block d-block Electron configuration [Xe] 4f 14 5d 6 6s 2.
Is yttrium a main group element?
Other Main Group Elements A few scientists include the group 3 elements (scandium and yttrium) and sometimes the lanthanides and actinides.
Is tellurium a main group element?
The oxygen family, also called the chalcogens, consists of the elements found in Group 16 of the periodic table and is considered among the main group elements. It consists of the elements oxygen, sulfur, selenium, tellurium and polonium. These can be found in nature in both free and combined states.
Is rubidium a representative element?
The S Block elements or the elements in columns 1A and 2A on the left of the periodic table include Hydrogen (H), Lithium (Li), Sodium (Na), Potassium (K). Rubidium (Rb), Cesium (Cs), Francium (Fr), Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba) and Radium (Ra).
What are Group 11 elements called?
The Group 11 is composed of copper (Cu), silver (Ag), and gold (Au). Silver and Au belong to the so-called noble metals. All these metals occur in variable oxidation stages, mainly +1, and +2, (Table II-11.1).
What are Group 7 elements called?
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What are Group 12 elements 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).
Which element is a main group metal?
All transition elements are metals, but main group elements are classified into metallic and nonmetallic elements. Germanium and polonium may also be included as metals. Boron, silicon, germanium, arsenic, antimony, selenium, and tellurium exhibit some metallic characteristics and they are sometimes called metalloids.
Is Gallium a main group metal?
gallium (Ga), chemical element, metal of main Group 13 (IIIa, or boron group) of the periodic table.
Is holmium a main group element?
Its oxide was first isolated from rare-earth ores by Cleve in 1878. The element’s name comes from Holmia, the Latin name for the city of Stockholm. Elemental holmium is a relatively soft and malleable silvery-white metal. Holmium Group group n/a Period period 6 Block f-block Electron configuration [Xe] 4f 11 6s 2.
Is bromine a main group element?
Elements such as fluorine, chlorine, bromine, iodine, and astatine belong to Group 17, the halogen group. Halogens therefore react most vigorously with Group 1 and Group 2 metals of all main group elements.
