HOMEWORK9 Formation of a Chemical Bond Formation of a Chemical Bond Learning Goal: Teunderstand how achmeal bond foned n molecules A chemical bond is a strong electrostatic atraction between two or more aloms. It is formed ether by a transler ol electrons or by a sharing of electrons such that each parcipating a approaches a near noble-gas configuration A bond formed by a ranaler of electrons is called an ionie bond A bond formed by a sharing of electrons is called a covalent bond Acoondinale covalent bond is formed when an electron-tich atom donates a pair of electrons to an electron deficient atom Part A When two hydrogen alfoms approach each other to form a chemical bond, diffeent interactions occur between the atoms Idensfy the correct statements with respect to the interactions involved in the formation of chemica bord Check all that apply Hints when he atoms of H approach each other, each electron is abaded by toofw ncleus. when hwo atoms of H are rthi-y far apart they show attractive interactors when two atons of H approach each oee, each electron repels fe oeer nudeus. when two storms ofHapproach each oter, the two nude repel each other When two stans of H approach each other, the elechons tract each other.

Initially when the two hydrogen atoms are far apart, there is no interaction between them However, as the two atoms come closer together, atraction and repulsion between the attractive forces must overcome the repulsive forces As the altractive force increases, the attractiv Irces are balanced by the epis ve rees vd a statie hydrogen mo ecule sfo med.

The correct statements are
1. when two atoms of H approach each other, each electron is attracted by the other nucleus
2. when two atoms of H approach each other, they show attractive interactions.
4. when two atoms of H approach each other,the two nuclei repel each other
