Questions and Answers
What is the main reason atoms bond with each other?
What is the main reason atoms bond with each other?
- To share their protons
- To achieve a stable arrangement of outer-shell electrons (correct)
- To create energy
- To form larger molecules
Why are noble gases generally unreactive?
Why are noble gases generally unreactive?
- They easily lose electrons
- They have a stable arrangement of electrons in their outer shell (correct)
- They have no electrons
- They form strong ionic bonds
How does a sodium atom achieve a stable outer shell?
How does a sodium atom achieve a stable outer shell?
- By creating a covalent bond with another atom
- By losing its only outer electron (correct)
- By forming a triple bond
- By gaining two electrons
What happens to the electron configuration of a sodium atom when it becomes a sodium ion?
What happens to the electron configuration of a sodium atom when it becomes a sodium ion?

Flashcards
Why do atoms bond?
Why do atoms bond?
Atoms bond to achieve a stable arrangement of outer-shell electrons, similar to the non-reactive noble gases.
Why noble gases don't bond?
Why noble gases don't bond?
Noble gas atoms already have a stable outer electron configuration, making them unreactive.

Study Notes
Atomic Bonding
- Atoms bond to achieve a stable arrangement of outer-shell electrons.
- Atoms aim for 8 electrons in their outer shell (or 2, for atoms with only one shell).
- Noble gases are unreactive due to their stable outer electron arrangements.
Why Noble Gases Don't Bond
- Noble gas atoms have stable outer electron shells.
- This stability makes noble gases unreactive.
Sodium Atom Stability
- Sodium atoms have one electron in their outer shell.
- To achieve a stable outer shell (8 electrons), sodium loses one electron.
- This loss transforms a sodium atom into a sodium ion (Na+).
