What elements are non-metals?
What elements are nonmetals? The elements that are generally considered other nonmetals include hydrogen, carbon, nitrogen, phosphorus, oxygen, sulfur, and selenium. Nitrogen and phosphorus are included in the subgroup pnictogens. Oxygen, sulfur, and selenium are included in the subgroup chalcogens.

Where are the nonmetals?
right
The nonmetals or non-metals are a group of elements located on the right side of the periodic table (except for hydrogen, which is on the top left).
Which is not a non metal?
Nonmetals or non-metals are chemical elements that does not have the properties of a metal. Some are gases including: hydrogen, helium, oxygen, nitrogen, fluorine, neon or radon and many others.
What is non metal answer?
Non-Metals are the elements that do not conduct heat and electricity, are not shiny and have dull appearance. They are neither malleable nor ductile. For example: Carbon, Sulphur, Phosphorus, Silicon, Hydrogen, Oxygen etc.

How many nonmetals are in the modern periodic table?
What are the four properties of nonmetals?
The nonmetal element group consists of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur and selenium . Hydrogen acts as a nonmetal at normal temperatures and pressure and is generally accepted to be part of the nonmetal group. Properties of nonmetals include: dull, not shiny.
What are the types of nonmetals?
Four common nonmetals are sulfur nitrogen, selenium, and bromine. The seven metalloids are boron , silicon, germanium , arsenic, antimony, tellurium, and polonium. The three types of elements occupy their own places in the Periodic Table .
What is the difference between metals and nonmetals?
While metals are good conductors of electricity and heat, non-metals are poor conductors. Unlike non-metals, metals are ductile, which means they can be stretched into wires. Another difference between metals and non-metals, is that the former has a metallic luster, while the other does not.
What are the characteristics of non – metals?
Nonmetals display some or all of the following characteristics: dull appearance. usually brittle. poor conductors of heat and electricity. usually less dense, compared to metals. usually low melting point of solids, compared with metals.
