What are the 4 types of elements?
Science Lesson: Earth, Water, Air, and Fire. The ancient Greeks believed that there were four elements that everything was made up of: earth, water, air, and fire. This theory was suggested around 450 BC, and it was later supported and added to by Aristotle.
What groups are main group elements?
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 P Block in periodic table?
The p-block is the region of the periodic table that includes columns IIIA to column VIIIA and does not include helium. There are 35 p-block elements, all of which are in p orbital with valence electrons. The p-block elements are a group of very diverse elements with a wide range of properties.
What are non – group elements?
The nonmetal element group is a subset of these elements. 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. Properties of nonmetals include: dull, not shiny.
Which are the basic metals in chemistry?
Basic Metals Aluminum Gallium Indium Tin Thallium Lead Bismuth Nihonium: probably a basic metal Flerovium: probably a basic metal Moscovium: probably a basic metal
What is the meaning of group or family in chemistry?
In chemistry, a family is a group of elements with similar chemical properties . Chemical families tend to be associated with the vertical columns on the periodic table.
What elements have similar chemical properties to magnesium?
Answer: The correct answer 1: beryllium and magnesium. Both elements appear on the same group (II),and therefore have the most similar chemical properties.
