B. because the other options are different sciences (biology and entomology)
Answer: Option D is the correct answer.
Explanation: A carbon atom is a group 14 element that has atomic number 6. In order to attain stability carbon atom needs to be bonded to four electrons of another atom. A carbon atom usually bonds with another atom by sharing of electrons.
Solution or homogeneous mixture
The transfer of energy that occurs when a force is applied over a distance is WORK.
Hope this helps!
An atom of fluorine would possess 7 valence electrons as it is found in group 7 of the periodic table.
The group number in this case corresponds to the number of valence electrons present.
So, for instance, because Chlorine is also found in group 7, it would also have 7 valence electrons.
