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.

What is the name of the group that is the least reactive?
The noble gas group is the group of elements that are the least reactive .
What is the most reactive family periodic table?
The family that contains the most reactive metals are the alkali metals.
What are the least reactive metals on the periodic table?
Silver, gold, and platinum are metals with the least reactivity. They are found in nature.
Which family or group is the least reactive family or group?
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.
What is the least reactive element in Group 7?
This is because group 7 elements react by gaining an electron. As you move down the group, the amount of electron shielding increases, meaning that the electron is less attracted to the nucleus. For this reason, fluorine is the most reactive halogen and astatine is the least reactive of the halogens.
Which is the least reactive metal?
Gold is the least reactive metal.
Which is the least reactive non metal?
Helium is the least reactive non metal. Helium is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert gas.
Why is neon the least reactive element?
Neon, along with helium, argon, krypton and xenon, make up the group known as noble gases. These are the most stable and least reactive elements due to having full valence shells (the outer shell has the max number of electrons, two for helium, eight for the rest).
Which is the least reactive alkali metal?
The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive.
Which two groups families are the most reactive?
The two most reactive families of elements are the halogens and the alkali metals.
What are the 3 most reactive metals?
The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.
How do you know which element is least reactive?
The reactivity of an element can be determined by looking at the electron configuration of the element. The least reactive elements are those who have a full outermost valence shell ie they have 8 electrons in the outer shell so elements such as helium, neon, radon or the transition elements.
What is the least reactive noble gas?
Overview. Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. They include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). Noble gases are the least reactive of all known elements, because with eight valence electrons, their outer energy levels are full.
Which is the least reactive metal gold or platinum?
Platinum is the least reactive metal. So, platinum is less reactive than gold.
