How to find the central atom in a compound?
To find the central atom in a compound, identify the element that is least electronegative or least likely to form multiple bonds. This element is usually located towards the center of the molecule. In a Lewis structure, the central atom is typically the one that is connected to the most other atoms.
Is fluorine a positive molecule?
F2 is a neutral diatomic molecule, it often reacts to form compounds that have a fluoride F-, ion.
How is the of the second element in a covalent molecule changed?
The ending of the second element is changed to -ide
Is XeF2O polar?
XeF2O is a polar molecule. This is because of the presence of lone pairs on the central xenon atom, causing an uneven distribution of electron density. This leads to a net dipole moment, making the molecule polar.
What of these elements is the most electronegative?
Fluorine is the most electronegative element.

Which element is the most electronegative element?
The most electronegative element fluorine.
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.
What is the charge of a dipolar molecule?
actually a bipolar molecule(dipole) in isolation doesn't have any charge.But when it comes near a electropositive or electronegative element/ion it develops pseudo negative charge(for electropositive ion) or pseudo positive charge(for electronegative ion).
What is the atomic number of the most electronegative element?
the atomic number for flourine, the most electronegative element, is 9.
What of these elements is the most electronegative?
Fluorine is the most electronegative element.
What determines the order in which the component elements of binary compounds are written?
The normal convention is to write the part of the molecule that is less electronegative first then the part that is more electronegative. This has the effect of writing the cation then the anion. For instance, carbon dioxide is written as CO2. Why not write it as O2C and call it dioxygen monocarbide? Once again, we write the less electronegative element first which is C in the example. That is the way to deal with all of the binary molecular compounds.
What causes water to be a polor molecule?
Oxygen is a highly electronegative element that draws electrons towards itself causing an imbalance of charge and hence polarity.
Which element is given first the more electronegative or less electronegative?
fluorine is most electronegative and cesium is least electronegative
