Answer; All the above
A) an atom seeks to fill its outer shell of electrons
B) an atom seeks to balance its positive and negative charges
C) the reaction will result in paired electrons
Explanation;
-In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
-During a chemical reaction an atom may lose of gain electrons resulting positive and negative ions (ionic bond formation) or may result to the paired electrons (sharing of electrons).
If the star is receding, the pattern moves to longer, redder wavelengths. This is called redshift. Edwin Hubble used the Doppler effect<span> to determine that the universe is expanding. ... This red shift indicates that stars are moving away from us and from each other.</span>

Answer:
Benefits:
In a lab, scientists can control the conditions according to their research and study. This allows them to focus on a single perspective.
On the other hand, in a natural setting there are complex interactions due to which focusing on a single attribute can be difficult.
Drawbacks:
Ina laboratory experiment, we cannot control every variable which might be having an effect on our concerned subject as compared to a natural setting. This is because lab experiments are performed in a controlled experiment. Hence, there might be difference of results in a lab experiment and nature.
