No. Burning is generally something that occurs at an elevated temperature. Liquid nitrogen is a cryogenic material; it is terribly cold. It is possible for liquid nitrogen to turn some metals as brittle as glass or a candy cane, making them easy to break. But it cannot burn metal, thermically nor chemically.
Liquid nitrogen is an element.
Bob discovered liquid nitrogen.
Liquid nitrogen is condensed gaseous nitrogen. When a gasis condensed it is called to be in liquid state.
No. Nitrogen is not flammable.
Nitrogen must be cooled to a very low temperature to become liquid nitrogen. At room temperature, liquid nitrogen will change from the liquid phase to the gas phase. Therefore, if the skin is treated with liquid nitrogen, the liquid nitrogen will almost instantly become a gas and evaporate away from the skin. It is impossible to "leave" it on the skin, as this reaction is almost instantaneous and no liquid nitrogen is left behind.
Liquid nitrogen, which is very cold, is often used to freeze warts and skin cancers quickly so that they can be safely removed from the skin. This process is sometimes loosely called "burning off" the skin blemishes so treated, but it is not burning in the chemical sense. Any other cold liquid that does not adversely react with skin could be used as well, but liquid nitrogen is usually cheaper than any other available liquid. The chemical properties of nitrogen, other than non-reactivity, have nothing to do with this use of the element.
Liquid nitrogen.
It is Acid
No. Nitrogen does not irritate skin. But liquid nitrogen is extremely cold, and it can damage and kill skin (and other) tissue. It is a bad idea to allow your skin to come into contact with liquid nitrogen. Note: Some warts are "frozen" in an effort to remove them. In a clinical setting, liquid nitrogen is sometimes used to super-cool an instrument so the wart can be frozen. But this is a medical procedure and is done by professionals. Liquid nitrogen is not something that should be looked upon as a "toy" or "recreational plaything" by anyone.

You are touching nitrogen right now- almost 80% of the air touching you is nitrogen gas. Quite safe. LIQUID nitrogen is another matter- it is an extremely cold liquid that will freeze your skin on contact.
It's not bad for you as it is what they use to freeze off warts from your skin.
