Which of the following statements is not true of the process of nuclear fission? a. it is the process used in most nuclear power plants. b. it only occurs in very small atoms with low mass. c. it involves the splitting of an atom’s nucleus. d. it can occur in a chain reaction.

Option (B) is the correct answer.

Explanation:

Nuclear fission is defined as a process in which a heavy nucleus is bombarded with a neutron(s) and it results in the formation of two nuclei with equivalent mass and magnitude and neutrons along with emission of energy.

Some characteristics of nuclear fission are as follows.

Thus, we can conclude that out of the given options, the statement it only occurs in very small atoms with low mass is not true of the process of nuclear fission.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
