Which of the general statements below is true about main group group A elements?
Main group group A elements are also known as representative elements and they include elements in the s and p blocks of the periodic table. They typically form ions with a positive charge by losing electrons and tend to be found in nature in their elemental forms. These elements are involved in a wide range of chemical reactions due to their relatively low ionization energies.
What is the common name for group 1 elements?
The common name for Group 1 elements is alkali metals. These elements include lithium, sodium, potassium, rubidium, cesium, and francium, and they are highly reactive with water.
Is calcium a main group element?
Yes, calcium is a main group element. It belongs to Group 2 of the periodic table, which is also known as the alkaline earth metals. Main group elements are those in the s and p blocks of the periodic table.
Are the elements Cu a representative elements?
Yes, copper (Cu) is considered a representative element. Representative elements also called main-group elements, are the elements found in the s and p blocks of the periodic table. Copper is located in Group 11 and period 4 of the periodic table, making it a representative element.
How is boron different from other elements in group 13?
Boron is the only element in group 13 that is a metalloid, meaning it shares properties of both metals and nonmetals. It has a unique structure due to its small atomic size and high ionization energy compared to its group members. Boron also forms covalent compounds instead of ionic compounds like other group 13 elements.
Which group of the main group elements contains the largest elements - Atomic Radius?
Group-1 has largest atomic radius. It decreases across a period
What elements have more predictable properties main group elements or transition elements?
main group elements
What are in the main group of elements?
Groups 1, 2, and 13 - 18 are the main group elements, also called the representative elements.
Which group contains only representative elements?
Representative elements, also known as main group elements, include groups 1, 2, and 13-18 on the periodic table. Group 1 contains alkali metals, group 2 contains alkaline earth metals, and groups 13-18 contain p-block elements. These groups are called representative elements because they display a wide range of chemical properties.
What are the main group group elements?
the noble gases
Which of the following groups of elements are in the main group alkali metals non metals transition elements or halogens?
Alkali metalsNonmetalsHalogens
What are elements main features?
The main group elements are groups 1, 2, and 13 - 18.
What are the main-group elements?
the noble gases
Is rhenium a non-metal?
all elements that are not main group elements are metals, and since rhenium is not a main group element, it is a metal. Hope this helped!
Which groups compose the mains group elements?
Main group elements have elements from groups 1 and 2, except hydrogen and groups 13 to 18. Main group elements are elements in groups who's lightest elements are shown by helium, lithium, boron, beryllium, carbon, nitrogen, oxygen, and fluorine.
The representative elements are usually called?
The representative elements are usually called the main group elements or the Group A elements. They are located in the leftmost and middle sections of the periodic table, excluding the transition metals.
The modern periodic table of elements contains main groups.?
18
