There are lots of potential pairs of nonmetals. One can't help but feel this was probably a multiple choice or matching question and you haven't given us the options to choose from; what you want to do is look for two elements both of which are on the right hand side of the Periodic Table.
Baron, Silicon, Arsenic, Tellurium, Astatine, Polorium, Antimony, Germanium
everything in the right hand side of the periodic table, including hydrogen which is on the left part of the table
Look at the elements on the right side of the periodic table. Most tables already have a distinction between metals, nonmetals and metalloids in the table.
Nonmetals are: H, He, Ne, Ar, Kr, Xe, Rn, O, N, I, Br, F, Cl, C, P, S, Se.
Oxygen
Elements are classified as metals, metalloids and nonmetals.
nitrogen and phosohorus
Most of the 92 naturally occurring elements can be classified as either metals or non-metals. Metalloids, also known as semi-metals, are a smaller group of elements that have properties of both metals and non-metals.
he grouped the table into metals, non metals and gases.
Elements are classified as metals, non-metals and metalloids and this classification is not for compounds. Iron sulfide is a compound, the question is non-applicable as it is neither a metal or a non-metal.
Elements are classified as metals, metalloids and nonmetals.
The elements classified as non-metals are in right direction. They are present in group-15,16,17.
The elements are classified as metals and non metals. Apart from this, there are elements that are metalloids, transition elements, inert in nature.
Elements can be classified as metals, metalloids, and non-metals.
Elements are usually classified as metals, non-metals, or metalloids.
Apart from metals and non-metals, metalloids are also present. Transition elements are also present in periodic table.
The majority of the elements in the p-block are non-metals.
The vast majority of elements in the periodic table can be classified as metals. Metals make up the s-block, d-block, and f-block of the periodic table. There are even a few elements in the p-block with metallic properties called metalloids.
Yes, there's no other classes.
nitrogen and phosohorus
Most of the 92 naturally occurring elements can be classified as either metals or non-metals. Metalloids, also known as semi-metals, are a smaller group of elements that have properties of both metals and non-metals.
Add non-metals to the mix and yup you've just summarized the entire periodic table of elements.
