Are noble gases each a different color?
Each of the noble gasses glows in its own colour when exposed to high voltage; for example helium becomes pink, krypton glows yellow/green, xenon shines in lavender blue and argon in light blue.
What does argon smell like?
Argon has no smell. It is a colorless gas. It has no taste. It, being inert, is non-toxic.
Can you breathe argon?
Inhalation: This gas is inert and is classified as a simple asphyxiant. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death. Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue.
Why is argon dangerous?
Argon is nontoxic and largely inert. It can act as a simple asphyxiant by displacing the oxygen in air to levels below that required to support life. Inhalation of argon in excessive amounts can cause dizziness, nausea, vomiting, loss of consciousness, and death.

Why is argon a good gas?
Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning.
Why is argon a noble gas?
The noble gases, in order of their density, are helium, neon, argon, krypton, xenon and radon. They are called noble gases because they are so majestic that, in general, they don’t react with anything. For this reason they are also known as inert gases.
Why Magnesium is not a noble gas?
The noble gas configuration of magnesium is [Ne]3s². It has two more protons (and two more electrons) than neon. The s orbitals fill first. Magnesium in Period 3, so the electrons go into the 3s orbital.
Why beryllium is not a noble gas?
Although the second shell has also two electrons but it is not complete . It can still acomodate six more electrons . Therefore the element beryllium does not reprsetn a noble gas element. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
