FAQ: What is a main group element?

What is considered a main group element?

In chemistry and atomic physics, the main group is the group of elements (sometimes called the representative elements) whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements.

What blocks make up the main group elements?

The s-block and p-block together are usually considered main-group elements, the d-block corresponds to the transition metals, and the f-block encompasses nearly all of the lanthanides (like lanthanum) and the actinides (like actinium).

What are the main group elements located on the periodic table?

Groups 1, 2, and 13–18 are the main group elements, listed as A in older tables. Groups 3–12 are in the middle of the periodic table and are the transition elements, listed as B in older tables.

Is gold a main group element?

The elements in group VIIA are called the halogens and the elements in group VIIIA are called the noble gases or the inert gases. The metals in group IB (copper, silver and gold) are sometimes called the coinage metals. The columns with A (IA through VIIIA) are called the main group elements.

Is RB a main group element?

The most important unifying principle in describing the chemistry of the elements is that the systematic increase in atomic number and the orderly filling of atomic orbitals lead to periodic trends in atomic properties. Li, Na, K, Rb, and Cs are all group IA elements, also known as the alkali metals.

What is the S block on the periodic table?

The sblock in the periodic table of elements occupies the alkali metals and alkaline earth metals, also known as groups 1 and 2. Helium is also part of the s block. The alkali metals include: lithium, sodium, potassium, rubidium, cesium, and francium.

What are Dblock elements?

D block elements are the elements which can be found from the third group to the twelfth group of the modern periodic table. The valence electrons of these elements fall under the d orbital. D block elements are also referred to as transition elements or transition metals.

Which element is a main group nonmetal?

The nonmetal element group consists of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur and selenium. Hydrogen acts as a nonmetal at normal temperatures and pressure and is generally accepted to be part of the nonmetal group.

How do most of the main group metals behave in reactions?

The most active metals are so reactive that they readily combine with the O2 and H2O vapor in the atmosphere and are therefore stored under an inert liquid, such as mineral oil. These metals are found exclusively in Groups IA and IIA of the periodic table. Metals in the second class are slightly less active.

Which element has the electron configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p²?

Germanium has the electron configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p².

What are the Group B elements?

They are located in the middle of the periodic table between Group IIA and Group IIIA. They provide transition between the “base formers” on the left and “acid formers” on the right. The most common transition metals include chromium, manganese, copper, iron, coblat, zinc, silver, mercury and gold.

Which element is most likely to bend without breaking?

Cobalt is the element which is most likely to bend without breaking. Explanation: Elements can be of two type: metals and nonmetals. Metals are ductile that is the can be drawn into small wires and they can be bent without breaking.

Are transition metals shiny?

Transition metals are also high in density and very hard. Most of them are white or silvery in color, and they are generally lustrous, or shiny. The compounds that transition metals form with other elements are often very colorful.
