Oxygen has more protons in its nucleus compared to helium, creating a stronger pull on electrons, leading to higher electronegativity. Additionally, oxygen has a smaller atomic size, allowing it to hold on to electrons more tightly, enhancing its electronegativity compared to helium.
What else can I help you with?
Which is more electronegative O or Se?
Oxygen (O) is more electronegative than Selenium (Se) because oxygen is higher up and to the right in the periodic table, which increases its ability to attract and hold onto electrons in a chemical bond.
Is calcium more electronegative than oxygen?
No, oxygen is more electronegative than calcium. Oxygen has a higher electronegativity value on the Pauling scale compared to calcium, indicating it has a stronger tendency to attract electrons in a chemical bond.
Fluorine is more electronegative than oxygen?
That is correct. Fluorine is the most electronegative element on the periodic table, meaning it has a strong ability to attract electrons in a chemical bond. Oxygen is also very electronegative but not as much as fluorine.
Why carbon is less electronegative than oxygen?
Carbon is less electronegative than oxygen because oxygen has a greater nuclear charge and smaller atomic size, leading to a stronger attraction for electrons. This makes oxygen more effective at attracting and holding onto electrons compared to carbon, resulting in a higher electronegativity for oxygen.
Why H2O is more polar than H2S?
H2O is more polar than H2S because oxygen is more electronegative than sulfur, resulting in a greater difference in electronegativity between the hydrogen and oxygen atoms in H2O compared to H2S. This difference creates a stronger dipole moment in H2O, making it more polar overall.
Which is more electronegative O or Se?
Oxygen (O) is more electronegative than Selenium (Se) because oxygen is higher up and to the right in the periodic table, which increases its ability to attract and hold onto electrons in a chemical bond.
Which element in H20 is more electronegative?
Oxygen is more electronegative than hydrogen in H2O. Oxygen has a stronger pull on electrons due to its higher electronegativity, causing it to attract the shared electrons more strongly in the water molecule.
Is oxygen more electronegative than sulfur?
Yes, oxygen is more electronegative than sulfur. This is because its electronegativity is about 3.44, while sulfur's is about 2.58.
Is calcium more electronegative than oxygen?
No, oxygen is more electronegative than calcium. Oxygen has a higher electronegativity value on the Pauling scale compared to calcium, indicating it has a stronger tendency to attract electrons in a chemical bond.
What element has a bigger electronegative sulfur or oxygen?
Oxygen is more electronegative. Oxygen is above sulfur on the Periodic Table. As you go up on the table electronegativity increases. The only thing more electronegative than oxygen is fluorine.
Is chlorine more electronegative than oxygen?
No, oxygen is more electronegative than chlorine. Oxygen has a higher electronegativity value on the periodic table (3.44) compared to chlorine (3.16). Electronegativity is a measure of an atom's ability to attract electrons in a chemical bond.
Fluorine is more electronegative than oxygen?
That is correct. Fluorine is the most electronegative element on the periodic table, meaning it has a strong ability to attract electrons in a chemical bond. Oxygen is also very electronegative but not as much as fluorine.
Which is the most electronegative element lithium or oxygen?
Oxygen is more electronegative than lithium. Electronegativity refers to an element's ability to attract electrons in a chemical bond, and oxygen has a higher electronegativity value compared to lithium on the periodic table.
Why fluorine cannot form oxyacids?
Fluorine can not form oxyacids because fluorine is more electronegative than oxygen, and oxyacids are formed only from elements that are less electronegative than oxygen.
Why carbon is less electronegative than oxygen?
Carbon is less electronegative than oxygen because oxygen has a greater nuclear charge and smaller atomic size, leading to a stronger attraction for electrons. This makes oxygen more effective at attracting and holding onto electrons compared to carbon, resulting in a higher electronegativity for oxygen.
Is oxygen more electronegative than phosphorus?
According to the Pauling scale, the electronegativity of oxygen is 3.44 while that of phosphorus is 2.19. Therefore oxygen is more electronegative than phosphorus, i.e. the oxygen atom has a greater tendency to attract electrons towards itself than the phosphorus atom. Fluorine is the most electronegative element in the periodic table, with an electronegativity value of 3.98.
Which is more polar h2s or h2o?
H2O (water) is more polar than H2S (hydrogen sulfide) because oxygen is more electronegative than sulfur. This results in a greater difference in electronegativity between the hydrogen and oxygen atoms in water, leading to a more polar molecule.
