Why do elements with positive oxidation number easily combined with those having a negative oxidation number?
Elements with positive oxidation numbers have excess electrons that they can share or transfer with elements having negative oxidation numbers that have electron deficiencies. This transfer or sharing of electrons allows the elements to achieve a more stable electron configuration, forming compounds through the formation of ionic or covalent bonds.
When oxidation number positive or negative?
In general, oxidation numbers are positive when an atom loses electrons (oxidation) and negative when an atom gains electrons (reduction). The oxidation number reflects the charge that the atom would have if the electron was completely transferred.
Does a metal or nonmetal have both positive and negative oxidation numbers?
A metal typically has only positive oxidation numbers, while a nonmetal can have both positive and negative oxidation numbers. Metals tend to lose electrons (positive oxidation numbers) to form cations, while nonmetals can gain or lose electrons to form a variety of oxidation states.
The oxidation number of an atom is shown with a negative number?
No, the oxidation number of an atom is typically shown as a positive or negative number (or zero) that represents the charge it would have in a compound or ion. Positive oxidation numbers indicate loss of electrons, while negative oxidation numbers indicate gain of electrons.
What is the oxidation number of an ion?
The oxidation number of an ion is the charge of the ion, which is determined by the number of electrons gained or lost by the atom to achieve a stable electron configuration. Positive ions have oxidation numbers that equal their charge, while negative ions have oxidation numbers that are the negative of their charge.

Do metals have both positive and negative oxidation numbers?
No, the can only have positive oxidation numbers
Is the electron charge positive or negative?
The electron charge is negative.
What is the oxidation nu?
Oxidation number is oxidation states of an element. It can be positive or negative.
The oxidation number of an atom is shown with a negative number?
No, the oxidation number of an atom is typically shown as a positive or negative number (or zero) that represents the charge it would have in a compound or ion. Positive oxidation numbers indicate loss of electrons, while negative oxidation numbers indicate gain of electrons.

Positive ions have oxidation numbers that equal their charge, while negative ions have oxidation numbers that are the negative of their charge.
Is a property that can have both positive and negative oxidation numbers a metal or nonmetal?
A property that can have both positive and negative oxidation numbers typically corresponds to a metal. Metals tend to lose electrons to form positive oxidation states and gain electrons to form negative oxidation states, while nonmetals typically gain electrons to form negative oxidation states.
How does the oxidation number indicate if an electron will be lost or gained?
The increase in oxidation number indicates loss of electrons, while a decrease indicates gain of electrons. For example, if an atom's oxidation number increases from +2 to +4 in a reaction, it has lost two electrons. Conversely, if the oxidation number decreases from +4 to +2, it has gained two electrons.
Does an electron have a positive charge?
No, an electron has a negative charge.
How do oxidation numbers determine if an element is a metal or a nonmetal?
Generally, metals attain positive oxidation numbers only. Non metals can have either positive or negative oxidation states. If an oxidation number is a negative value, it can be deduced that it's a non metal element.
