Question

select the correct answer from each drop-down menu. a carbon atom forms bonds with other atoms by valence electrons in order to attain a stable configuration. drop - down options: two, three, four; buttons: reset, next

Explanation:

1. For the first drop - down: A carbon atom has 4 valence electrons and tends to form 4 covalent bonds with other atoms to achieve a stable electron configuration (octet rule, as carbon needs 8 electrons in its outer shell and it has 4, so it shares 4 electrons by forming 4 bonds).
2. For the second drop - down (assuming the common context of covalent bonding in carbon): Carbon forms bonds by sharing valence electrons. (The process of covalent bonding involves sharing electrons to achieve a stable electron configuration. Carbon, with 4 valence electrons, shares these electrons with other atoms. So the action is "sharing".)

Answer:

First drop - down: four
Second drop - down: sharing
