Does an element that loses electrons when bonding with other atoms have a negative oxidation number?
No. The lower (or 'more negative') the oxidation number, the more electrons the atom has. This is because the oxidation number is a measure of the charge on that molecule and, since electrons have negative charge, more of them give a more negative oxidation number. So if an atom loses electrons during bonding, it has lost some of its negative charge - giving it a more positive oxidation number.
What is a positive oxidation number?
Positive oxidation number implies that electrons are generally lost by the element.
Why there is a plus 2 in oxidation number in carbon?
Carbon has +2 oxidation number in Carbon monoxide. It gets this oxidation number when it loses or shares two electrons.
When a species in a chemical reaction loses electrons The oxidation number increases?
Yes.
Oxidation number is the same as?
The oxidation number is the same as the charge that the atom has. If the atom usually loses an electron, then it is losing a negative charge and having more positive making it a + 1. If the atom loses two electrons, then the oxidation number would be +2. The same thing with gaining electrons, then there would be more negative charges then positive. If the atom gains one electron, then the oxidation number would be - 1. If the atom gains two electrons, then the oxidation number would be - 2. I hope that this was helpful.

What is name given to the number of electrons an atom gains loses or shares?
Oxidation number

When a neutral atom undergoes oxidation the atoms oxidation state?
increases as it loses electrons
What does the selected oxidation states number represent?
The Charge of the ion of that element. How many electrons it has lost or gained. Ex. Oxygen= the accepted oxidation number is -2 because it gains 2 electrons therefore its charge is negative Ex. Beryllium= the accepted oxidation number is +2 because it loses electrons therefore its charge is positive. I think
What the meaning of the oxidation?
Oxidation has three main meanings in science, 1) An substance gaining oxygen 2) A substance loses electrons 3) A substance increases in oxidation number (ox. State)
When an atom gains or loses electrons it is called an?
covalent/ionic bonding.
What is the result of this oxidation?
When a substance is oxidized, it loses electrons. Thus, its oxidation state becomes more positive.
Which electrode loses electrons and which half reaction occurs here?
The anode electrode loses loses electron and oxidation half reaction occurs at it.
