Which of the following best describes a fission reaction involving lithium? (1 point)
a. two lithium atoms form bonds with each other, absorbing a large amount of energy.
b. the nuclei of lithium atoms join together to form heavier isotopes, and energy is released.
c. an atom of lithium absorbs electrons, undergoes an increase in energy level, and splits into fragments.
d. the nucleus of an atom of lithium splits, resulting in smaller fragments and the release of a large amount of energy.

The nucleus of an atom of lithium splits, resulting in smaller fragments and the release of a large amount of energy. Therefore, option D is the correct answer.

Nuclear fission is a reaction in which a heavy nucleus splits into two or more smaller nuclei. Some characteristics features of nuclear fission are,

Thus, we can conclude that, in nuclear fission lithium atom is splits into smaller fragments with the release of a large amount of energy. Therefore, option D is the correct 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.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
