Explain why hydrogen atoms can form a covalent bond but helium atoms cannot.
Explain why hydrogen atoms can form a covalent bond but helium atoms cannot.
Homework Answers
Ans:
1.Hydrogen atom is having 1S1 elctronic configuration.while bonding it share the unpaired electron to form COVALENT BOND. It is having low ionisation enthalpy.
2.Helium atom is having 1S2 elctronic configuration and it is noble element which is highly stable element.
So Helium atom never shares its electrons to form covalent bond.and it needs high Ionisation enthalpy also.Helium forms weak vanderwall bond only.

Explain why hydrogen atoms can form a covalent bond but helium
atoms cannot.

In the video, you can see that when two hydrogen atoms approach one another, a covalent bond is formed due to the overlap of the 1s orbital of each hydrogen atom. The process by which a covalent bond is formed is explained with the help of the graph of potential energy versus the distance between the two atoms. Identify which of the following statements are correct. Potential energy decreases as the repulsive forces increase. When two atoms are very far...

A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
