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 elements oxidation number?
The oxidation number of an element is a measure of the number of electrons that an atom of that element has gained or lost to achieve a stable electron configuration. It is a value that is assigned to an element in a compound to help track the flow of electrons in chemical reactions. Oxidation numbers can be positive, negative, or zero, depending on whether the element has lost, gained, or shared electrons.
If an element gains electrons what type of oxidation number does it have and how do you know?
If an element gains electrons, it has a negative oxidation number. The oxidation number is determined based on the number of electrons gained or lost by an atom in a compound. The rule is that in ionic compounds, the oxidation number of an element is equal to the charge it would have if it were an ion.
What oxidation number does an atom have if it loses two electrons when bonding?
+2 for example, Be, Mg, Ca, Sr or any other group 2 element in a compound with a group 6 element
Why do nonmetals have a negative oxidation number?
Nonmetals tend to gain electrons to achieve a stable electron configuration and become more like noble gases. This results in a negative oxidation number because they gain electrons rather than lose them.
DID OXIDATION AND REDUCTION PROCCED SIMULATANEOUSLY?
Oxidation is an element or an ion getting a positive charge by removing valence electrons and Reduction is an element or an ion getting a negative charge by gaining free electrons. In chemical reactions reduction occurs by gaining the free electrons emitted by oxidation. Therefor oxidation and reduction proceed simultaneously.Oxidation is an element or an ion getting a positive charge by removing valence electrons and Reduction is an element or an ion getting a negative charge by gaining free electrons.

What is meant by oxidation number?
The oxidation number of an atom is a measure of the amount of electrons it has gained, lost, or shared in a chemical reaction. It helps in determining the extent of an element's electron loss or gain, which provides insight into its reactivity and bonding patterns in chemical compounds. The oxidation number is represented as a positive or negative integer.
What is oxidation number of an element?
The charge an element would have if it lost or gained electrons
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.
What is the oxidation number of nonmetals?
Nonmetals typically have negative oxidation numbers, which can vary depending on the element and the specific compound. They tend to gain electrons to achieve a stable electron configuration, resulting in negative oxidation states.
When an element gives an electron to another element is called?
This is usually part of the bonding process called ionic bonding.
Why do elements such as PN and S have posotive oxidation numbers in some compounds but negative in others?
The oxidation number of an element can vary depending on the compound it is a part of. This is due to differences in electronegativity and bonding patterns with other elements in the compound. In some compounds, elements like phosphorus (P) and sulfur (S) may have positive oxidation numbers because they lose electrons to form cations, while in other compounds, they may have negative oxidation numbers by gaining electrons to form anions.
What is an oxidation number in chemistry?
An oxidation number is a positive or negative number assigned to an element in a chemical compound to indicate its degree of oxidation or reduction. It helps in determining how electrons are transferred during a chemical reaction. Oxidation numbers can be used to identify the oxidation state of an element in a compound.
