Which is less electronegative than silicon?

There are many elements less electronegative than silcon. Look at the periodic table, and pretty much everything (with a few exceptions) to the left of, and below silicon will be less electronegative.


What element is less electronegative than silicon?

Aluminum is less electronegative than silicon.


Is phosphorus electronegative?

Yes, phosphorus is electronegative. It is a nonmetal element located in the nitrogen group of the periodic table. However, phosphorus is less electronegative than elements like oxygen and fluorine.


Is barium more electronegative than beryllium?

Beryllium is more electronegative than barium. Elecronegativity decreases as you move down the periods of the periodic table. Since Ba is further down the table than Be in the same group, Be would be more electronegative.


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.


Is the electronegativiy of barium larger or smaller than that of strontium?

The electronegativity of barium is less than that of strontium.


Are period 1 elements more electronegative than period 2 elements?

No, period 1 elements are not more electronegative than period 2 elements. Electronegativity generally increases across a period from left to right, so elements in period 2 are generally more electronegative than elements in period 1.


Barium element is larger or smaller than caesium?

Barium is smaller than caesium. Different elements have different atomic radii, with caesium having a larger atomic radius compared to barium.


Which is more electronegative?

Fluorine is more electronegative than chlorine because it is closer to the top right corner of the periodic table.


Which is more reactive barium magnesium or beryllium?

Barium is more reactive than magnesium, and beryllium is less reactive than both. Reactivity generally increases as you move down a group on the periodic table, so barium is more reactive than magnesium due to its position in the same group.


Why the chlorine does not form hydrogen bond as the nitrogen do in spite the chlorine is more electronegative than nitrogen?

Hydrogen bonding occurs between hydrogen and a highly electronegative atom such as nitrogen, oxygen, or fluorine. Chlorine is less electronegative than these elements, so it is not able to form hydrogen bonds with hydrogen. In hydrogen bonding, the hydrogen atom must be covalently bonded to a highly electronegative atom.


What is oxide an element or a compound?

An oxide is a compound that contains oxygen and at least one other element that is less electronegative than oxygen.
