Main group metals tend to lose electrons, forming a cation with the same number of electrons as the nearest noble gas. A main group nonmetal tends to gain electrons, forming an anion with the same number of electrons as the nearest, previous noble gas
Group 18 (Noble Gases) contains the largest main group elements because they have the highest atomic numbers and largest atomic radii among the main group 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.
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.
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.
There is a total of 17 elements in those groups.

Group 18 (Noble Gases) contains the largest main group elements because they have the highest atomic numbers and largest atomic radii among the main group elements.
Groups 1, 2, and 13 - 18 are the main group elements, also called the representative elements.

There are three sets of ions where the charges are given correctly: Group 1 elements (e.g., Na+), Group 2 elements (e.g., Mg2+), and aluminum (Al3+). These ions have fixed charges that do not vary.
The main group elements are groups 1, 2, and 13 - 18.
All the elements in the periodic table of elements are electrically neutral; they do not have charges as elements, although they have the potential to engage in chemical reactions that will turn them into charged ions, in most cases. The different groups tell you what kinds of chemical reactions the elements are capable of, not what kind of charge they have.

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!
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 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.
