How are positive and negative oxidation numbers assigned in a compound?
Positive oxidation numbers are assigned to elements that lose electrons in a compound, while negative oxidation numbers are assigned to elements that gain electrons. The oxidation number is determined by the number of electrons gained or lost in forming the compound. The sum of oxidation numbers in a compound is always zero for a neutral compound, or equal to the charge of the ion in an ionic compound.
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.
Which elements show both positive and negative oxidation states?
Transition metals such as iron, copper, and chromium exhibit various oxidation states, both positive and negative, due to the filling and emptying of their d orbitals. They can donate or accept electrons, allowing them to form different ions with varying 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.
Why do elements with a positive oxidation number easily combine with those having a negative oxidation number?
Elements with positive oxidation number easily combined with those having a negative oxidation number because opposite oxidation number attracts each other.

What are the oxidation states of group 18 elements?
0, neither positive or negative. They are the noble gases, and as such, very unreactive

Do metals have both positive and negative oxidation numbers?
No, the can only have positive oxidation numbers
What is the oxidation nu?
Oxidation number is oxidation states of an element. It can be positive or negative.

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.
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.
What is the most common oxidation number for group three on the periodic table?
Generally third A group elements in the periodic table exhibit +3 oxidation state but Boron exhibit negative oxidation state also . The stable oxidation state of Tl is +1. It exhibit +3 also but +1 is more stable than +3. RGUKT IIIT NUZVID N091528
What are oxidation numbers are written as?
... as positive or negative numbers
