In order from most to least similar:
1. Germanium
2. Lead
3. Phosphorus
4. Chlorine
The elements in the same column as the element you have are the most similar. The rows are not. For example, though chlorine and magnesium are in the same row, they have very different properties, whereas chlorine and fluorine more similar
The answers are as follows:
1. TRUE, <span>The energy in a nuclear reaction comes from the transformation of mass to energy.
</span>
2. TRUE, <span>Although both fission and fusion generate energy, fusion produces much more energy than nuclear fission and produces less nuclear waste
</span>
3. TRUE, <span>In certain types of atomic bombs, a fuel, like plutonium-239, is bombarded with neutrons to create an uncontrolled nuclear reaction that splits the nuclei of the fuel.
</span>

Answer:
Iron (Fe)
Explanation:
The reactivity series shows a series of metals reactivity from lowest to highest. Based on the arrangement of metals in the reactivity series, iron is placed above tin and below zinc, this means that iron is more reactive than tin but less reactive than zinc. This means that iron would displace tin ions in a solution whereas zinc would displace iron ions in a solution.
The reactivity of metals is due to the stability of metals in their electron configurations as atoms and as ions.
