Which of the following is a chemically inert?

Noble gases
Noble gases are chemically inert.

Which of the following atoms would be chemically inert or unreactive?

Group 8A — The Noble or Inert 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 metal is chemically inert?

Osmium and iridium are chemically inert in ambient conditions. Platinum and gold can be dissolved in aqua regia.

What is the most inert element?

helium
Elements with shells that are already full and have no electrons to lend are called noble gases—and helium, the smallest of these, is considered the most inert.

Is o2 inert?

Ahh. Hooray for oxygen, the element that keeps much of life on Earth humming. … 8 on the Periodic Table of the Elements is a colorless gas that makes up 21 percent of Earth’s atmosphere. Because it’s all around, oxygen is easy to dismiss as dull and inert; in fact, it’s the most reactive of the non-metallic elements.

Why inert gases are chemically inert?

When elements react, their atoms complete their outer shells by losing, gaining, or sharing electrons . The atoms of noble gases already have complete outer shells, so they have no tendency to lose, gain, or share electrons. This is why the noble gases are inert and do not take part in chemical reactions.

What is a chemically inert element?

In chemistry, the term chemically inert is used to describe a substance that is not chemically reactive. … 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).

What is meant by chemically inert?

An inert chemical substance is one that is not generally reactive. This is a synonym for “inactive” with respect to chemical reactions. Inert has a non-chemical meaning of being unable to move or resist movement; for example, “the accident victim was laying on the ground, inert.”

Why are some elements chemically inert?

Lewis postulated that inert gas atoms are chemically inert because they hold 8 valence electrons. The valence electron pattern in these atoms is called an inert gas electron configuration. … The atoms do this by ionizing (gaining or losing electrons) or by sharing an electron pair with another atom.

What is an example of inert?

The definition of inert is slow or having no action or power to move. An example of inert is a slug that is standing still. Unable to move or act; inanimate. Sluggish or lethargic.

What is inert material?

Inert materials are classed as ‘waste that does not undergo any significant physical, chemical or biological transformations and is unlikely to adversely affect other matter with which it comes into contact’. To you and I, this waste includes brick, concrete, hardcore and subsoils which cannot be reused/recycled.

Is platinum chemically inert?

Platinum is chemically inert and will not oxidize in air at any temperature. It is resistant to acids and is not attacked by any single mineral acid but dissolves readily in aqua regia. The metal is rapidly attacked by fused alkali oxides and by peroxides and will react with fluorine and, at red heat, with chlorine.

Is carbon chemically inert?

Elemental carbon is an inert substance, insoluble in water, diluted acids and bases, as well as organic solvents. At high temperatures it binds with oxygen to form carbon monoxide or dioxide.

Which granular materials are chemically inert?

Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete.

Is nitrogen chemically inert?

Nitrogen molecule is diatomic and the two notrogen atoms are linked by triple bond (N=N). … As the bond dissociation enthalpy is very high (946 kJ mol-1), it is not possible to cleave the triple bond so easily.

Is Neon A inert?

neon (Ne), chemical element, inert gas of Group 18 (noble gases) of the periodic table, used in electric signs and fluorescent lamps.

Is sodium inert?

Sodium is a chemical element with the symbol Na (from Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal.

Is argon reactive or inert?

Argon is a colourless, odourless gas that is totally inert to other substances. Argon is often used when an inert atmosphere is needed. It is used in this way for the production of titanium and other reactive elements.
