How are negative ions made?

Negative ions are typically created when molecules or atoms gain one or more extra electrons, resulting in a negative charge. This can occur through processes such as sunlight, waterfalls, and lightning, which can ionize particles in the air. Negative ion generators can also be used to artificially produce negative ions by discharging high-voltage electricity into the air.


Is combustion a form of oxidation or reduction?

In all Redox reactions some things are oxidized (meaning those elements lose electrons) and some things are reduced (meaning those elements gain electrons). The phrase to remember is OIL RIG - Oxidation Is Losing Reduction Is Gaining.


Do electrons have a negetive charge?

Yes! they are Electrons produce negative charge, and protons produce positive charge, while neutrons produce no charge at all.


When does a redox reaction produce electricityOnly when an electrical device is attached Whenever electrons are transferred between atoms When electrons are transfered and a pathway for electrons is providedWhenever a pathway for electrons is provided?

A redox reaction contain oxidation and reduction half reaction you can prove it by using oxidation numbers


What charge does an exces of electrons produce?

An excess of electrons would produce a negative (-) charge since these particles are negative. If you imagine a scale with negative and positive weights, more negative weights would make the scales tip towards the negative end.


What does oxidation of a primary alcohol produce?

Minimal oxidation will produce an aldehyde, stronger oxidation will produce a carboxylic acid, and complete oxidation will produce carbon dioxide and water.


What charge does a sodium electron produce?

You are confused about two things. First of all, electrons do not produce a charge, they simply have a charge, which is negative one. Secondly, the electrons in a sodium atom are exactly the same as any other electrons. All electrons in the entire universe are the same. There are no sodium electrons, there are just electrons. And they all have a charge of negative one.


What reactions produce electrons?

Oxidation reaction.


Does an atom with negative charge nucleus exist?

No, only protons and neutrons exist in the nucleus of an atom. Electrons are what produce a negative charge.


Does flurine form a positive or negative ion?

Fluorine is negative and will produce a negative ion.


Why must oxidation numbers be assigned to the elements before writing a chemical formula?

The oxidation numbers of the elements in a chemical formula, some of which will be positive and others of which will be negative, when multiplied by the numbers of atoms with each oxidation number, must produce products that add to a net result of zero.
