Question

When atoms bond, their electron configuration become "stable" resembling what type of group on the periodic table?

1) Noble gases
2) Alkali metals
3) Transition metals
4) Halogens

Answer 1

Atoms bond to achieve a stable electron configuration similar to that of noble gases, following the octet rule which aims for eight electrons in their valence shell.

Step-by-step explanation:

When atoms bond, their electron configurations become "stable," resembling the electron configuration of noble gases. Noble gases have filled valence shells, which make them highly stable and non-reactive. Other atoms achieve stability by gaining or losing electrons to result in a filled valence shell, thus attaining a noble gas-like electron configuration. This process is driven by the "octet rule" which is a general guideline that atoms tend to have eight electrons in their valence shell, imitating the electron configuration of noble gases such as helium, neon, or argon.
