The symbols of the nonmetals are as follows:
Hydrogen: H
Helium: He
Carbon: C
Nitrogen: N
Oxygen: O
Fluorine: F
Neon: Ne
Phosphorus: P
Sulfur: S
Chlorine: Cl
Argon: Ar
Selenium: Se
Bromine: Br
Xenon: Xe
Iodine: I
Krypton: Kr
Astatine: At
Radon: Rn
all are non metals
Their hardness will be less than that of metals but more than that of non metals. Hence the name, semi metals or metalloids.
bromine
They have properties of metals and non-metals, and also have properties that are around '1/2' of both. An example is silicon, which has a high melting point and is solid (metallic properties). However it is very brittle and it forms an acidic oxide (non-metal). It is a semi-conductor.
The symbol for boron on the periodic table is "B." It is the fifth element, with an atomic number of 5. Boron is a metalloid, which means it has properties of both metals and non-metals. It is commonly used in glass and ceramics, as well as in various chemical applications.
Arsenic (symbol As) is a metalloid. It exhibits properties of both metals and non metals.

Non metals
The symbols of the metals come from their Latin names. For example, iron's symbol Fe comes from its Latin name "ferrum". Similarly, gold's symbol Au comes from its Latin name "aurum".
