What is the main group on the periodic table?

What is the main group on the periodic table?

The main group elements are groups 1, 2, and 13-18 on the periodic table. The main group elements are the chemical elements belonging to the s-block and p-block on the periodic table. These are elements in group 1 and group 2 (s-block) and groups 13 through 18 (p-block).

What is a main group element in period 2?

O is a main group element in period 2, group 16 of the periodic table, in the p-block.

Is Na a main group element?

Abstract. 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 is Group 4 in the periodic table?

titanium
Group 4 is the second group of transition metals in the periodic table. It contains the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). The group is also called the titanium group or titanium family after its lightest member.

How many main group elements are there?

Groups 1, 2 and 13 to 18 constitute the main group. Sometimes groups 3 and 12, as well as the lanthanides and actinides (the two rows at the bottom), are also included in the main group.

Is there a main group element in Period 5?

Rubidium. Rubidium is the first element placed in period 5. It is an alkali metal, the most reactive group in the periodic table, having properties and similarities with both other alkali metals and other period 5 elements.

What is group 5A called?

Group 5A (or VA) of the periodic table are the pnictogens: the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metal bismuth (Bi).

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 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….
