Which family of elements is the most unreactive Why?

Which family of elements is the most unreactive Why?

Which group of elements is the most unreactive, why? Group 8, the noble gases, because they have all of their energy levels filled.

What is an unreactive element?

Most Group 8 or 18 elements that appear in the last column of the periodic table (Helium, Neon, Argon, Krypton, Xenon and Radon) are classified as inert (or unreactive). These elements are stable in their naturally occurring form (gaseous form) and they are called inert gases.

What group of elements are the most unreactive?

noble gases
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.

What is the most unreactive element?

Helium
Helium is the most unreactive element of the periodic table.

Why are some elements unreactive?

When elements react, their atoms complete their outer shells by losing, gaining, or sharing electrons . Atoms of group 0 elements already have stable arrangements of electrons. This means that they have no tendency to lose, gain, or share electrons. This is why the noble gases are unreactive.

Which family on the periodic table is the least reactive?

Noble gases
Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. Noble gases are the least reactive of all elements. That’s because they have eight valence electrons, which fill their outer energy level.

Which is the most unreactive element?

Which family is composed of metals nonmetals and metalloids?

Groups 13–16 of the periodic table contain one or more metalloids, in addition to metals, nonmetals, or both. Group 13 is called the boron group, and boron is the only metalloid in this group. The other group 13 elements are metals. Group 14 is called the carbon group.

What’s a family of elements?

An element family is a column of elements on the periodic table. Each member of a family has the same number of valence electrons. Family members share similar chemical and physical properties. An element family is also called an element group.

What family of elements is relatively unreactive and why?

What family of elements is relatively unreactive and why? The noble gases because their valence shell is has 8 electrons. Many chemical reactions take place because atoms don’t have a full outer/valence electron shell.

How many unreactive elements are there in the periodic table?

The six unreactive elements, of which Argon is a member, as a class are referred to as the “Noble” or Inert Gases, found on the rightmost column of the Periodic Table. As elements, none are created through chemical reactions, but may be isolated through such reactions.

Which of the following is a nonreactive element?

An nonreactive element in the Periodic Tableof Elements is an element that has their last energy level (shell) filled with 8 valence electrons. Some examples of nonreactive elements are Helium, Neon, Argon, Krypton, Xenon, and Radon.

Why is argon called an unreactive element?

Argon It is called an unreactive element because it has a stable electronic configuration and does not share its electrons with other atoms. Argon, discovered in 1894, makes up 0.93% of the earth’s atmosphere, which makes it the third most abundant gas. It is a byproduct of the production of oxygen and nitrogen.
