∙ 13y agoOxygen is highly electronegative. When hydrogen forms a bond with oxygen, the oxygen atom has the ability to pull the electrons in the bond closer to itself causing the molecule to be polar. This means the hydrogen is slightly positive and the oxygen is slightly negative.

∙ 8y agoDue to higher electro negativity the oxygen atom will pull the electron cloud towards itself. In the Modern Periodic Table, the size of atom decreases while going left to right across a period. The electronegativity increases with decrease in size, due to increase in charge to size ratio (exception: Noble Gases which have slightly larger atoms than halogens and have complete octet).
You can take analogy of two men of equal heights. One is a wrestler and the other is a normal guy. Both shake hands and then try to pull each other. Obviously the wrestler will pull other guy's hand towards him. This is because he has higher strength to size ratio than the other person.
This is similar to a higher electronegative elements pulling lesser electronegative element's electron cloud towards itself. This leads to a polar compound with partial negative charge towards electronegative element and partial positive charge towards the less electronegative/electropositive element.

Does magnesium have a higher electronegativity than calcium?
Yes, Mg is more electronegative than Ca. By the Pauling scale Mg has an electronegativity value of 1.31 while Ca has 1.00. The higher the value, the more electronegative the element is. The electronegativity of the elements generally decrease down group II (the alkaline earth metals).

Can nitrogen form hydrogen bonds?
No element on its own can form hydrogen bonds. Only compounds where hydrogen is bonded to nitrogen, oxygen, or fluorine. Hydrogen bonded to carbon and sulfur (selenium?) can also participate in strong hydrogen bonding when these atoms are bound to electronegative elements or ligands. (Eg. HCN, CHCl3, CH3COSH)

What is the result when oxygen bonds with lithium?
Lithium oxide is formed which has ionic bond between two Li+ ions and a O2- ion.
How is oxidation number different from valence electrons?
Valence is how many bonds an atom can form. Oxidation number can be though of as being similar to the charge on an ion, and is based on the difference in electronegativity between bonded atoms. If something is bonded to a more electronegative element, its oxidation state is positive, and if it is with a less electronegative on the state is positive. In a neutral substance the sum of the oxidation states is always zero. Valence and oxidation states are related, though.Example: In formaldehyde (CH2O) hydrogen has a valence of 1, oxygen a valence of 2, and carbon a valence of 4. Carbon is more electronegative than hydrogen, and less electronegative than oxygen. As a result, each hydrogen atom has an oxidation state of 1+ and the oxygen is in the 2- oxidation state. This puts carbon in an oxidation state of 0.
What is the differences in electronegativity would result in an ionic bond?
Generally a difference of 1.4 in electronegativity would result in an ionic bond.
Is CLF5 ionic?
No - although Fluorine is the most electronegative element, chlorine is also electronegative. The result is a trigonal bipyramidal covalent compound
Why is the covalent bond between O and H considered polar?
Oxygen has an electronegativity of 3.44 Hydrogen has an electronegativity of 2.2 So Oxygen attracts the electrons so the oxygen side of the bond is more negative as the electron are closer to it, this forms permanent dipoles as parts of the molecule are have opposing charges. And that is a polar covalent bond and non polar bond is is where you have two elements with the same EN and the electron is equidistant from them. You can have non polar molecules with polar bonds for example carbon dioxide whitch is linear in shape so the charges cancel each other out.
What ion will lithium form?
Like other alkali metals, lithium has a single valence electron which it will readily lose to form a cation, indicated by the element's low electronegativity. As a result, lithium is easily deformed, highly reactive, and has lower melting and boiling points than most metals. These and many other properties attributable to alkali metals' weakly held valence electron are most distinguished in lithium, as it possesses the smallest atomic radius and thus the highest electronegativity of the alkali group. Double and triple charged cations are also possible.
Is The bond between H and O is polar covalent?
Oxygen is a highly electronegative atom while hydrogen is a lot less electronegative as compared to oxygen. Thus, the oxygen atom will attract the electrons in the covalent bond towards itself. As a result, the oxygen atom gains a slight negative charge due to the closer proximity of electrons while the hydrogen atom gains a slight positive charge because its electrons are now further away from the protons. Thus, the molecule formed will have slightly charged ends, which makes it polar.
What happens when electrons are unequally shared in a covalent bond?
Unequal sharing results when there is significant difference in electronegativities. The more electronegative atom(s) draws bond electrons closer, leaving the less electronegative atom(s) slighty positive. The result of unequal sharing of electrons is the formation of polar bonds.
Why is FCl polar but F2 is not?
A molecule is polar is a result of differences in electronegativity; that is, one atom has a stronger pull on electrons than another. Flourine (F) is more electronegative than chlorine (Cl), and so tends to pull electrons to its side of the molecule. This makes FCl polar. F2 consists of two atoms of fluorine, which are identical and thus have the same electronegativity. Therefore, the molecule is nonpolar.
What is the oxidation number of W in WO4-2?
In anions that contain oxygen along with a less electronegative element, each oxygen atoms is assigned an oxidation number of -2. Therefore, a WO4-2 anion requires the tungsten atoms to have an oxidation number of +6, to result in the specified charge of the anion.
