What does the octet rule state?
What does the octet rule state?
- Atoms ideally exist in a state of instability.
- Atoms need to have eight electrons in their outermost shell for stability. (correct)
- Atoms should give up their electrons to achieve stability.
- Atoms should have eight electrons in their innermost shell.
What is the main difference between covalent and ionic bonds?
What is the main difference between covalent and ionic bonds?
- In covalent bonds, atoms give up electrons to each other, while in ionic bonds they keep their electrons.
- Covalent bonds are formed by the transfer of electrons, while ionic bonds share electrons.
- Covalent bonds involve sharing electrons, whereas ionic bonds involve one atom giving up its electrons to another. (correct)
- In ionic bonds, atoms share electrons equally, while in covalent bonds they transfer electrons.
Why is the octet rule important in predicting chemical bonds?
Why is the octet rule important in predicting chemical bonds?
- It allows chemists to predict the possible bonds formed by main group elements based on the number of valence electrons. (correct)
- It helps in determining the atomic mass of a substance.
- It helps determine the number of protons in an atom.
- It indicates the number of neutrons an atom has.
