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 considered an oxide because it is composed of oxygen combined with another element, which in this case is hydrogen. Hydrides typically refer to compounds where hydrogen is bonded to a more electropositive element, such as in sodium hydride (NaH).
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?
Hydrogen stored in a fuel tank filled with lithium nitride is safer in an accident because the lithium nitride can chemically bond with the released hydrogen, reducing the risk of fire or explosion. This reaction helps to prevent the rapid release of hydrogen gas in the event of a leak or impact, making it a safer storage option compared to a high-pressure hydrogen cylinder.
Does iron react with tin nitrate?
Yes, iron can displace tin from tin nitrate through a single displacement reaction to form iron(II) nitrate and tin.
What is the word equation for the reaction between hydrogen and fluorine?
The word equation for the reaction between hydrogen and fluorine is "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?
Fluorine is the most electronegative halogen, making it the least electropositive. Among the other halogens (chlorine, bromine, iodine), iodine is the most electropositive.
What is the value of H in chemistry?
In chemistry, H usually represents the element hydrogen. It is the first element in the periodic table with the atomic number 1.
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?
Francium is the most electropositive element, as it readily loses its outermost electron to form a positive ion. It is located at the bottom of the alkali metal group in the periodic table and is highly reactive.
Is fluorine electropositive?
No, fluorine is not electropositive. It is one of the most electronegative elements, meaning it has a strong tendency to attract electrons in a chemical bond.
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.
