Is. Hydrogen a metal or non metal?

Answer 1

The answer is both, keep in mind that hydrogen is an exception. This is science and here's the scientific answer.

Hydrogen can be pressed into a liquid metal when under extreme atmospheric pressures like those on planets of Saturn and Jupiter (their pressure is 300 million + times that of Earth.)

Under typical conditions however, hydrogen is a nonmetallic gas.

Answer 2

Hydrogen is a non-metalic gas. It is sometimes described as a metaloid.
At very very low temperatures and very very high pressures hydrogen has all the properties of a metal, so is commonly considered to be a metal in these very unusual conditions.

Answer 3

Hydrogen is kind of a special case. Ordinary hydrogen does not exhibit the characteristic properties of metals. It's hypothesized that at high enough pressures hydrogen will convert to a metallic form.

Metallic hydrogen is speculated to have all kinds of interesting properties. For example, it may be liquid even at low temperatures, and it's possible that it will be a room-temperature superconductor.

In the ordinary chemical sense, hydrogen is sort of an AC/DC element; it can go either way. It forms hydrides with metals (thus acting like a nonmetal), and hydrogen compounds with strongly electronegative nonmetals (thus acting like a metal).

It's probably most accurate to say that a simple division between metals and nonmetals is not comprehensive enough to encompass hydrogen (or, for that matter, silicon or carbon or germanium or any of a number of other elements).

Hydrogen is a lot more likely to be found in compounds as a cation (metal) than as an anion (nonmetal), but this is partly because oxygen is both strongly electronegative and very common in the universe as a whole; hydrogen bonded to oxygen always has at least a partial positive charge.

Answer 4

non-metal

actually, under extreme pressure and low temperature, hydrogen is a metal ... clearly a vaporized metal (gas) under earth atmospheric conditions.

Answer 5

Hydrogen is a non-metal (but it is placed along with alkali metals as it has one valence electron similar to alkali metals).

Answer 6

Non-Metal
