Because in order for a subsance to undergo reduction and become an oxidizing agent, the substance must gain electrons. Non metals therefore gain electrons while they are in their pure form while metals loose electrons in their pure form.
Examples include:
non metals- Cl2 + 2e- -> 2Cl-
Br2 + 2e- -> 2 Br-
Metals- Sn -> Sn2+ + 2e-
Ni -> Ni2+ + 2e-

∙ 11y agoNonmetals have a higher effective nuclear charge, therefore they are more likely to gain electrons in a chemical reaction and metals are more likely to give electrons up. This makes nonmetals the better oxidezer

∙ 11y agoBecause non metals try to attract electrons. so addition of electron takes place. That means the process is reduction. so they are oxidising agents

What happens when hydrochloric acid and cooper mix?
Nothing. Copper does not react with non-oxidizing acids (such as hydrochloric acid) because it is a noble metal (meaning it resists corrosion when exposed to air). All noble metals are inert components when exposed to non-oxidizing acids.
What prefers to receive electrons in chemical reactions?
The outermost, known as the valance electrons.
Is hydrochloric acid a non-oxidizing acid?
No
What is non-reducing sugar?
Non-absorbable sugars are also called sugar alcohols. They are sweet-tasting, but are not readily absorbed from the intestine into the body. Most are manufactured for commercial use. Examples are non-caloric sweeteners, like sorbitol and mannitol, which are often used in candies and gums. Non-absorbable sugars may be prescribed as laxatives.
What is the similarities and differences between conduction in metals and nonmetals?
metals: 1) have 1-3 electrons in the outer shell of each metal atom 2) lose electrons easily 3) good reducing agents 4) good conductors of heat and electricity IN metaks electrons are free to move within a fixed array of positive ions, by colliding the electons can transfer heat through the lattice. non metals: 1) have 4-8 electrons in their outer shell 2) gain or share valence electrons 3) good oxidizing agents 4) poor conductors of heat and electricity For non metals, there are relatively few free electrons, so the phonon method dominates. A phonon is a quantum of vibrational energy, and by the combination of many phonons, heat is observed macroscopically.
What properties do non metals have in common?
Elements that are classified as non-metals are characterized by a tendency to undergo chemical reactions in which they acquire electrons; this compares to metals which tend to lose electrons. In slightly more technical terms, this means that non-metals are oxidizing agents and metals are reducing agents; when you mix metals and non-metals together, they tend to react with each other, in what is sometimes called a redox reaction (reduction and oxidation). Other than that, non-metals are generally softer (or gaseous) and less shiny than metals are, they generally do not conduct electricity as well as metals do, they do not have the silvery color of metals.

Is honey a reducing sugar or non reducing?
yes because honey is a monosaccharide All monosaccharides reduce weak oxidizing agents such as Cu2+ in fehlings's reagent.
Are metals most known elements?
yes metals are more common than non-metals
What prefers to receive electrons in chemical reactions?
The outermost, known as the valance electrons.
What was Dimitri Mendeleïevs contribution to chemistry?
The organization of the elements (metals, non-metals, and semi-metals) which is known as the Periodic Table Of Elements.

Are halogens metals or non non-metals?
Non metals
Group 7 elements are all metals or non metals?
Definitely NON-Metals. , othjerwise known as the HALOGENS.
What is the mixture of two or more non metals?
mixture of two or more non metal is known as alloy
Most of the 92 naturally occurring elements are metal non metal metalloids or none of the above?
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.
