What Element Is In Group 2 Period?

What element is in Group 2 period? Group 2A — The Alkaline Earth Metals. Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

What is main group elements in the periodic table?

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 makes 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 is the main group element in period 3?

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.

Why do group 2 elements form 2+ ions?

Reactions of Alkaline Earth Metals

All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge.

As radium is the last element in group 2, it is the most metallic or has the most metallic character in group 2.


Why do group 2 elements lose 2 electrons?

In this case, elements located in group 2 will always lose electrons to become cations. More specifically, they will always lose 2 electrons to form 2+ cations. For the other elements, losing 2 electrons allows them to have a stable octet configuration, i.e. 8 electrons in their outermost shell.
