Answer:

(b) Both have the same number of valence electrons.  

Step-by-step explanation:

We find the most striking chemical similarities between two Main Group elements when they are in the same Group of the Periodic Table.

Elements in the same Group have the same number of valence electrons.

(a) is <em>wrong</em>, because elements in the same group have <em>different masses</em>.

(c) is <em>wrong,</em> because atoms with the same number of protons belong to the s<em>ame element</em>.

(d) is wrong, because elements in the same Group must be in . <em>different Periods.</em>

in terms of amounts of energy and harmful radioactive waste produced , which of the following is the most accurate comparison of
Eddi Din [679]

Explanation:

Nuclear fusion produces more energy with less radioactive waste compared to nuclear fission process.

  • In nuclear fission, a radioactive decay occurs in which a heavy nucleus spontaneously disintegrates into two lighter nuclei and several neutrons with the release of energy.
  • Nuclear fusion occurs when small atomic nuclei combines into larger ones with the release of a large amount of energy.
  • Instability of a nuclide is enough to start up a nuclear fission reaction. In some instances, a heavy nuclide is bombarded with another nuclide.
  • In nuclear fusion, the activation energy required to start up is very great.

Nuclear wastes emanating from nuclear fusion process is least compared to that of nuclear fission.

Nuclear fusion produces more energy  compared to nuclear fission process.
