Question

How many elements are there in non-metal?
A 14
B 18
C 88
D 114

Answer 1

Hint: Metals are highly electropositive elements. Non-metals are electronegative elements. Metalloids have properties that are intermediate between highly electropositive metals and electronegative non-metals.

Complete Step by step answer: Nonmetals gain one more electron to form anions (negatively charged anions). The valence shell of non-metals contains 4-7 electrons. Non-metals have poor electrical and thermal conductivity. They do not have metallic luster. In other words, non-metals do not appear shiny. Non-metals are not sonorous. In other words, non-metals do not produce a ringing sound when another material hits these non-metals. Non-metals have high ionization energies and high electronegativity. Due to this, non-metals form covalent bonds through sharing electrons.
Out of the total 118 elements
The total number of elements present in the modern periodic table is 118.
The number of non-metals is 18. The number of metalloids is 7 and the number of metals is 93.
Most nonmetals are gases. These include elements such as (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon
The non-metal bromine is a liquid. The non-metals carbon, phosphorus, sulfur, selenium, and iodine are solids. The element astatine is the radioactive nonmetal.

Hence, the correct option is the option (B).

Note: In the modern periodic table, metals are present on the left-hand side and non-metals are present on the right-hand side. Metalloids are present on the zigzag line between metals and nonmetals.
