Because it has only one electron in its valence shell. Its valence shell holds two electrons so it really wants to share its electron to make a bond of two electrons two fill its valence shell. Thus it is the mose "electron-donating" element. Electronegative elements want electrons so hydrogen donates its electron thus hydrogen is electopositive.

How many hydrogen bonds can ammonia molecule forms?
Intramolecular forces; Hydrogen bonds occur in ammonia between the nitrogen and the hydrogen, NH3.Intermolecular forces:Hydrogen bonding between molecules occurs between the electronegative nitrogen atom (N) of one molecule of ammonia and an electropositive hydrogen atom (H) bonded to a nitrogen of different molecule of ammonia.
Does iron react with tin nitrate?
iron being highly electropositive it does not react with covalent compound formed by two electropositive elements. that is tin nitride.
Why would hydrogen stored in a fuel tank filled with lithium nitride be safer in an accident then a cylinder full of hydrogen?
S Elements are attracted to P element H20 for example, 2 elements combining Hydrogen with a Electronegative elements. If 2 Electropositive element come together they push away from each other. If you combine Hydrogen with Lithium they do both condense like (S + P) and repel like (S + S) its a phenomenon. These elements combine increasing the stability of hydrogen while increasing pressurized tanks. Its not talked about because its used in nuclear testing and weapons.
How copper can be extracted by hydrometallurgy but not zinc?
zinc is more electropositive and therefore is highly reactive metal.hence it can not be easily displaced from its solution of ZnSO4.on the other hand,copper is less electropositive and can be readily displaced from its solution more active metal such as zinc. Zn + Cu2+ ------> Zn2+ + Cu
Would calcium and aluminum form a compound?
Not by themselves, because they are both too electropositive. Together with oxygen, however, they form calcium aluminate.
What is it called when water attracts to other polar substances?
Cohesion. Oxygen is electronegative, and Hydrogen is electropositive.
What is the oxidation number of hydrogeon when it is combined with a metal?
Hydrogen is a non metal. Metals are electropositive than hydrogen. Therefore, hydrogen atoms in metal hydrides have oxidation number -1.
Why is hydrogen the only element not placed in a group on the periodic table?
due to its dual nature having both the characteristics of electropositive and electronegative
What is the value of H in chemistry?
'H' means Hydrogen.Hydrogen has 1 proton and 1 electron but no neurons.It is both an electropositive and electronegative element.
What explain is negative charge on the oxygen atom within the water molecule?
Oxygen atoms are highly electronegative and pull electrons away from the electropositive hydrogen atom.
Which halogen is more electropositive?
Flourine is most electropositive as it is smallest and has fewest shells to shield the positive charge of the nucleus.
Why Magnesium React with Hydrochloric Acid violently?
In general, acids react with metals in a replacement reaction, since metals can replace the hydrogen component of the acid. The more electropositive the metal is, and the stronger the acid it, the more energetic the reaction will be, and in the case of magnesium reacting with hydrochloric acid, we have a highly electropositive metal reacting with a very strong acid.
Acids combine with active metals to give off H2?
SINCE active metals are more electropositive than of hydrogen it undergoes an displacement reaction. 2Na+2HCl = 2NaCl + H2
What is the most electropositive element?
Cesium is the most electropositive stable element. Francium is more electropositive (at least in theory) but only about 30 grams exists on the entire planet as it is highly radioactive so no one has been able to check.cesium is most electropositive element in periodic table.Ceasium
How many bonds does hydrogen need?
Hydrogen "needs" an extra electron to achieve the noble gas configuration of helium. It therefore only "needs" one bond. It can do this either by shsring electrons in a covalent bond, or with very electropositive metals such as Lithium it forms a bond that is virtually ionic, with most electron density on the hydrogen.
What are the differences between Ionic Hydrides and Covalent hydrides?
Ionic hydrides are formed by the reaction of hydrogen gas with the most electropositive metals. (group 1 and 2 excluding Be and Mg) The reaction involves the forming of a crystal lattice (solid). Covalent hydrides are formed by weakly electropositive metals and are primarily gasses at room temperature.
Does iron react with tin?
iron being highly electropositive it does not react with covalent compound formed by two electropositive elements. that is tin nitride.
