Question

two hydrogen atoms interact to form a hydrogen molecule. classify the following statements that describe the stages of bond formation in a hydrogen molecule according to the predominant force existing between the two hydrogen atoms. drag the appropriate items to their respective bins. view available hint(s) the two hydrogen atoms start to combine to form a hydrogen molecule. the two hydrogen atoms approach each other to form a bond. the two hydrogen atoms form a stable hydrogen molecule. the potential energy of the system is positive. the internuclear distance between the two hydrogen atoms is less than the bond length. the two hydrogen atoms are very far apart. the potential energy of the system is minimum. attractive force is predominant between the two atoms. repulsive force is predominant between the two atoms. attractive and repulsive forces balance each other. there is no interaction between the two atoms

Explanation:

Step1: Analyze each statement

• "The two hydrogen atoms start to combine to form a hydrogen molecule": When atoms start to combine, the attractive force (due to electron - proton interactions) begins to dominate as they move towards each other.
• "The two hydrogen atoms approach each other to form a bond": As they approach, the attractive forces (electron - proton) are more significant than the repulsive forces (proton - proton and electron - electron at this stage of approach)
• "The two hydrogen atoms form a stable hydrogen molecule": In a stable molecule, the attractive and repulsive forces balance each other. The energy of the system is at a minimum.
• "The potential energy of the system is positive": When the potential energy is positive, it means that the repulsive forces (proton - proton and electron - electron) are more dominant. This can happen when the internuclear distance is less than the bond length (because as the atoms get too close, repulsions increase)
• "The internuclear distance between the two hydrogen atoms is less than the bond length": When the distance is less than the bond length, repulsive forces (proton - proton and electron - electron) are predominant
• "The two hydrogen atoms are very far apart": When atoms are very far apart, there is no significant interaction (the forces are negligible)

Answer:

• Attractive force is predominant between the two atoms: The two hydrogen atoms start to combine to form a hydrogen molecule, The two hydrogen atoms approach each other to form a bond
• Repulsive force is predominant between the two atoms: The potential energy of the system is positive, The internuclear distance between the two hydrogen atoms is less than the bond length
• Attractive and repulsive forces balance each other: The two hydrogen atoms form a stable hydrogen molecule
• There is no interaction between the two atoms: The two hydrogen atoms are very far apart
