Formation of a Chemical Bond
Chemical bonds hold atoms together in molecules. A chemical bond is a strong electrostatic attraction between two or more atoms. It is formed either by transfer of electrons or by sharing of electrons such that each participating atom approaches a near-noble-gas configuration.
A bond formed by transfer of electrons is called anionic bond whereas a bond formed by sharing of electrons is called a covalent bond. A coordinate covalent bond is formed when an electron-rich atom donates a pair of electrons to an electron-deficient atom. Chemical bonds explain why and how one atom interacts with another atom. What happens when two hydrogen atoms approach each other to form a covalent bond? List all that apply
1.) The internuclear distance between two atoms of H is known as the bond order.
2.) When the two atoms of H approach each other, the electrons attract each other.
3.) The potential energy required for bond formation is equal in magnitude to the bond-dissociation energy.
4.) When the hydrogen atoms are far apart, the energy of their interaction is zero.
5.) When the two atoms of H approach each other, the two nuclei repel each other.
6.) When the two atoms of H are infinitely far apart, they show positive interactions.
7.) When the two atoms of H approach each other, each electron is repelled by the other nucleus.
