Answer:
D. The nucleus of an atom of lithium splits, resulting in smaller fragments and the release of a large amount of energy.
Explanation:
Fission is the splitting of a nucleus, so this is the only option that involves fission.
A is wrong. Li atoms do not bond to form molecules. Instead, the nuclei are immersed in a sea of electrons.
B is wrong. The joining of two nuclei is fusion.
C is wrong. Adding an electron to an atom of lithium is not a nuclear reaction.
The mass of an atom comes from the protons and neutrons
that are found in the nucleus. The number of protons is the atomic number of an
element. To find the number of neutrons, subtract the atomic number from the
mass of an atom. The atomic number is 8 and the atomic mass is 16.

Answer:
Cold-blood animals are the animals that are not capable of regulating their body temperature,Cold blood animals included reptiles,fishes,amphibians,insects and other invertebrates.
When atoms bond together to form molecules, they share or give electrons. If the electrons are shared equally by the atoms, then there is no resulting charge and the molecule is nonpolar.
