Question

Is neon a “metal” or a “non metal” ?

Answer 1

Hint: Neon was found in $1898$ as one among the three uncommon inert elements left in dry air after nitrogen, oxygen, argon, and carbon dioxide were removed (together with krypton and xenon). Neon was the second of these three rare gases to be found, and its vivid red emission spectrum readily identified it as a new element.

Complete answer:
Neon is a chemical element with the atomic number $10$ and the symbol $Ne$. It is non-metal. It is classified as a noble gas. Under normal conditions, neon is a colourless, odourless, inert monatomic gas with a density of about two-thirds that of air. It belongs to group $18$ of the periodic table.
Applications of Neon
Advertising signs are made with neon lights that are reddish-orange in colour. It's also used in these types of lighting when a lot of other gases are required to generate a variety of colours.
Lightning arrestors, high-voltage indicators, television tubes, and metre tubes are among the other applications for neon.
Neon and helium are used to create gas lasers.
In various types of gas-filled electron tubes, the electronics industry uses neon alone or in combination with other gases.
Because helium is less soluble in blood than nitrogen at high pressure, marine divers utilise a mixture of helium and neon for breathing.

Note:
Because neon is non-reactive and does not form compounds, it poses no hazard to the environment and has no impact. This substance has no negative impact on the environment. Fluorine is an inert element that can be used to make unusual compounds with neon in laboratories. It also produces a hydrate that is unstable.
