Fluorine is highly electronegative, meaning it has a strong attraction for electrons. As a result, when fluorine forms compounds, it tends to gain an electron to achieve a full outer shell, leading to an oxidation state of -1. This consistent oxidation state of -1 for fluorine arises from its strong tendency to gain electrons in chemical reactions.

Use electronegativity values to determine the one element that has always has a negative oxidation number when it appears in any binary compound?
Fluorine always has a negative oxidation number when it appears in any binary compound because it is the most electronegative element on the periodic table. This means it attracts electrons strongly towards itself, leading to a negative oxidation state in chemical compounds.
What is the oxidation number of BrF3?
Br +3, balanced by 3 fluorines each with -1.
What is the oxidation number of o in o2?
The oxidation number is 0. The sum of all oxidation number in a molecule that has not charge is always 0. If it has a charge (ion negative or positive) then the sum must be equal to the charge number.
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 is fluorine's oxidation number always negative?
Fluorine is the most electronegative element, meaning it has a strong tendency to gain electrons in chemical reactions. This leads to a stable octet configuration, resulting in a negative oxidation number (-1) when forming compounds.
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 is the oxidation nu?
Oxidation number is oxidation states of an element. It can be positive or negative.
What is the oxidation number of BrF3?
Br +3, balanced by 3 fluorines each with -1.
What is the oxidation number of o in o2?
The oxidation number is 0. The sum of all oxidation number in a molecule that has not charge is always 0. If it has a charge (ion negative or positive) then the sum must be equal to the charge number.
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 is fluorine's oxidation number always negative?
Fluorine is the most electronegative element, meaning it has a strong tendency to gain electrons in chemical reactions. This leads to a stable octet configuration, resulting in a negative oxidation number (-1) when forming compounds.
What does the positive or negative oxidation number tell you about an ion?
The positive oxidation number indicates the number of electrons an ion has lost, while the negative oxidation number indicates the number of electrons gained. The oxidation number provides information on the charge of the ion and its ability to form chemical bonds.
What is an atom's oxidation number?
The oxidation number of an atom states how it shares its valence electrons with other elements (or ions or compounds). A neutral atom always has its oxidation number 0: it does not share any electrons. A cation has a positive oxidation number and that of anion is negative because they donate and attract electrons respectively.
What is the oxidation number F negative 1?
The oxidation number for F is usually -1 in compounds, such as in NaF where F has an oxidation number of -1.
What is an atoms oxidation number?
An atom's oxidation number is the charge it would have if electrons were transferred completely. It is a measure of the atom's ability to gain, lose, or share electrons in a chemical reaction. Oxidation numbers can be positive, negative, or zero.
What is the oxidation number of CuF2?
The oxidation number of copper (Cu) in CuF2 is +2. The oxidation number of fluorine (F) in compounds is almost always -1, and since there are two fluorine atoms in CuF2, the total negative charge is -2, which balances with the +2 oxidation state of copper.
