Which element can have both positive and negative oxidation state?
So Iodine (I) can exist in both positive and negative oxidation states.
Which of the following atoms can have both positive and negative?
Answer: The atom is (D) Cl.
Why iodine shows both positive and negative oxidation state?
iodine could exist in both the positive and negative oxidation states . the polarization and electronegativity of iodine is responsible for the negative oxidation state like NaI, AgI etc…. whereas when iodine combines with higher electronegative atoms it attains positive oxidation state like IF5 etc..
Which of the following elements can have negative oxidation state?
Fluorine has highest electronegativity among all known elements, so it shows only negative oxidation states.
Which element shows always a positive oxidation state?
Fluorine
The less electronegative one is given a positive oxidation state. Remember that fluorine is the most electronegative element with oxygen second….Working out oxidation states.
| element | usual oxidation state | exceptions |
|---|---|---|
| Fluorine | always -1 | |
| Chlorine | usually -1 | except in compounds with O or F (see below) |
Does boron show negative oxidation state?
Binary metal-boron compounds, the metal borides, contain boron in negative oxidation states. Each boron atom has a formal −1 charge and magnesium is assigned a formal charge of +2.
Which of the following shows negative oxidation states?
fluorine
Negative oxidation states are shown only by fluorine.
Which of the following element can have negative oxidation state?
Fluorine has highest electronegativity among all known elements, so it shows only negative oxidation states.
What elements most common oxidation state is negative 2?
The more electronegative element in a substance is given a negative oxidation state….Working out oxidation states.
| element | usual oxidation state | exceptions |
|---|---|---|
| Group 2 metals | always +2 | |
| Oxygen | usually -2 | except in peroxides and F2O (see below) |
Which group has both a positive and a negative oxidation state?
The group I-A and III-A group have both positive and negative oxidation state . In I-A group H (hydrogen) has negative oxidation state and positive oxidation state.In III-A group B(boron)
What determines the oxidation state of an element in a compound?
An element’s oxidation state is determined by its electronegativity with respect to the other elements in a compound. Nitrogen (3.0) for instance can bind with hydrogen (2.1), forming NH3 in which it has a negative oxidation state, or it can form NO2 with oxygen (3.5), in which case it is positive.
Which of the following elements has an oxidation number zero?
Each atom in an element either in its free or uncombined state holds up an oxidation number of zero. Clearly, each atom in H 2, Cl2, P4, Na, Al, O2, O3, S8, and Mg, has an oxidation number zero. The oxidation number of ions which comprise of only one atom is equal to the actual charge on the ion.
What are the oxidation numbers of Group 1 Group 2 elements?
Here we are going to summarize oxidation numbers of all elements in the periodic table into one group. Oxidation numbers of group 1 group 2 elements are studied. Hydrogen forms three oxidation states, -1 , 0 , +1. Oxidation number 0 occurs only in hydrogen molecule.
