A chemical bond is indeed the force that holds two atoms together within a molecule. This can be in the form of covalent bonds, where atoms share electrons, ionic bonds, where atoms transfer electrons and are held together by electrostatic forces, or metallic bonds, which involve a 'sea' of shared electrons. Therefore, option A is correct
The image provided is a multiple-choice question from a quiz about intramolecular forces, asking for the definition of a chemical bond. Here are the options given:
A. An intramolecular force holding 2 atoms together
B. An electrostatic force between a proton and an electron
C. An attractive force between 2 molecules
D. A gravitational force holding electrons in their orbits
The correct answer is:
A. An intramolecular force holding 2 atoms together
A chemical bond is indeed the force that holds two atoms together within a molecule. This can be in the form of covalent bonds, where atoms share electrons, ionic bonds, where atoms transfer electrons and are held together by electrostatic forces, or metallic bonds, which involve a 'sea' of shared electrons. The key term here is "intramolecular," which means "within a molecule."
Option B describes the electrostatic force that is part of what creates a chemical bond, but not the bond itself. Option C refers to intermolecular forces, which occur between molecules, not within them. Option D is incorrect because gravitational forces are not what hold electrons in their orbits around the nucleus.
