Why is fluorine the least electronegative element?

Why is fluorine the least electronegative element?

Electronegativity of Fluorine Fluorine is the most electronegative element because it has 5 electrons in it’s 2P shell. The optimal electron configuration of the 2P orbital contains 6 electrons, so since Fluorine is so close to ideal electron configuration, the electrons are held very tightly to the nucleus.

Which atom is more electronegative H or O?

The oxygen atom is more electronegative (it is better than hydrogen at attracting electrons, because it has more positively charged protons in its nucleus), and this makes it slightly more negative; consequently, the hydrogen atoms are unable to hold the electrons near to them, and become slightly more positive.

Is Argon more electronegative than chlorine?

In Period 3, sodium with 11 protons is the least electronegative element, and chlorine with 17 protons is the most electronegative element. You might expect argon (with 18 electrons) to be the most electronegative element in Period 3.

Is bromine more electronegative than oxygen?

You will have to look up the Pauling scale yourself, but the O atom, first row, and rightmost on the table, will be most electronegative, followed by nitrogen and bromine.

Is D more electronegative than hydrogen?

Here is the answer to your question: For Protium(1H1) it has one proton(+ve charged) & so it could attract the electrons effectively towards itself but in deuterium there is an added neutral charge in the form of a neutron which increases the size thus reduces the electronegativity tendency of the deuterium atom.

Is deuterium more stable than hydrogen?

H, or deuterium (D), is the other stable isotope of hydrogen. The nucleus of deuterium, called a deuteron, contains one proton and one neutron (mass number = 2), whereas the far more common hydrogen isotope, protium, has no neutrons in the nucleus.

What are the 3 isotopes of hydrogen?

There are three isotopes of the element hydrogen: hydrogen, deuterium, and tritium.
