The Main Group Elements Consists Of What Category Of Elements??

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.

Which element is a main group element?

Examples of main group elements include helium lithium boron carbon nitrogen oxygen fluorine and neon. Elements that are not main group elements are the transition metals (such as titanium copper and gold) the lanthanides (such as lanthanum and erbium) and the actinides (such as actinium and plutonium).

What are the main groups of elements called?

The elements can also be divided into two main groups the metals and the non-metals. Metals are typically have a metallic sheen (shiny) are malleable (bendable) and conduct electricity. Nonmetals typically do not show these properties. There are some elements that show some but not all of the metallic properties.

What is main group in chemistry?

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.

How do you identify the main group element?

The Main-Group Elements. Determine which of two main-group elements has: the more metallic character the higher ionization energy the larger atomic radius the higher electronegativity the more acidic oxide the more ionic hydride and the more ionic oxide.

How many main group elements are there?

18

The s- p- and d-block elements of the periodic table are arranged into 18 numbered columns or groups. The elements in each group have the same number of valence electrons. As a result elements in the same group often display similar properties and reactivity.

What is another name for main group elements?

The main group elements along with a few light transition metals are the most abundant elements in the universe solar system and on Earth. For this reason main group elements are sometimes known as representative elements.

What are Group 4 elements called?

Which block elements are called main group elements?

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.

Which element is a main group element with an odd atomic number?

alkali metals

All alkali metals have odd atomic numbers. They are considered to be more similar to each other than any other group in the periodic table. The compound ammonium has very similar properties to the heavier alkali metals.
