How do the atoms share electrons in molecule formation so that each atom appears to have a noble gas electron configuration?

Atoms tend to achieve noble-gas configurations by bonding covalently . Sharing electrons allows each atom to have a stable electron configuration. Mani-group elements can gain a noble gas configuration by filling their outermost s and p orbitals. They can do this by sharing electrons through covalent bonding.

here's the link to your question!

explanation:

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
