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.

Is water an oxide or a hydride?
Water is the oxyde of hydrogen - H2O.Added:I agree, though if 'seen' from the oxygen side it could be named as an hydride of Oxygen: OH2, (compare PH3, phosphorhydride) but it is rather unusual.
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.
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.
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.
What is the word equation for the reaction between hydrogen and fluorine?
Hydrogen + fluorine ---> hydrogen fluoride
What is it called when water attracts to other polar substances?
Cohesion. Oxygen is electronegative, and Hydrogen is electropositive.
Why is Hydrogen an electropositive element?
Hydrogen is considered an electropositive element because it has a single electron in its outer shell, allowing it to easily lose that electron and form a positive ion (H⁺). This tendency to donate its electron makes hydrogen behave similarly to alkali metals, despite being placed separately in the periodic table. Additionally, when hydrogen reacts with nonmetals, it typically forms covalent bonds by sharing its electron, which further emphasizes its electropositive character.
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
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.
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.
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 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
Is fluorine electropositive?
No, no, no... Fluorine is the most electronegative of all
Why you can place hydrogen in group 7?
When reacted with highly electropositive metals, a hydrogen atom can accept an additional electron to attain the electron configuration of the noble gas that has one more proton than itself. This is a defining characteristic of periodic table column VII B in a narrow form periodic table.
How do elements become electropositive or electronegaitive?
Elements become electropositive or electronegative based on their tendency to lose or gain electrons. Electropositive elements have a low electronegativity and readily lose electrons to form positive ions. Electronegative elements have a high electronegativity and tend to gain electrons to form negative ions.
Why is the bond between an electropositive and an electronegative atom ionic in natyre?
The bond between an electropositive and an electronegative atom is ionic because the electronegative atom attracts electrons from the electropositive atom, leading to the transfer of electrons. This transfer results in the formation of ions with opposite charges, which are held together by strong electrostatic forces.
