For some reason, a lot of people want to know what the element krypton looks like. It turns out that you look at krypton every day, although you may not actually see it. Krypton is a colorless, odorless gas that rarely reacts with other elements. A container full of krypton gas looks just like a container full of air.
We don't know; science is not developed enough for us to actually see an atom (just represent it really well on a computer screen).
A colourless, odourless, unreactive noble gas and a constituent of air
It is a colourless gas. So, in its pure form, you wold not see it!
The natural state of krypton is a gas.
What i can say is that it is invisible
It is not visible. It is a colorless, odorless gas.
The 84 is the number of protons and neutrons (nucleons) in the atomic nucleus of the isotope krypton-84. . As Kr has an atomic number of 36, the number of protons is 36, and in krypton -84 there are therefore 48 neutrons.
In their pure state, shiny and lustrous
Yes Krypton can be oxidized by using Fluorine, to produce Krypton(II) Fluoride [KrF2]. The Proton bombardment process is a fast method for a relatively large amount of this. A mixture of Kr and F2 is bombarded with proton beam, to produce KrF2
pure form
It is a colourless gas.
Protactinium has a metallic appearance.
What i can say is that it is invisible
It is not visible. It is a colorless, odorless gas.
Polonium has a metallic silvery appearance.
yes it is.
It's a soft, silvery grey metal.
Zirconium metal has a metallic appearance, as steel.
it has a somewhat flat yellowish color it doesn't shine like jewelry
No, it is a pure substance; it is an element
Krypton isn't poisonous. If you breathe pure krypton for more than a minute or two, though, you would die as a consequence of oxygen starvation - but it is the absence of oxygen that kills you, not the presence of krypton.
