These statements describe three different reactions.

1 - an atom shares electrons with another atom.
2 - the nucleus of an atom is split apart.
3 - an atom gains an electron from another atom.

which reaction(s) most likely release the greatest amount of energy?
1
2
1 and 3
2 and 3

Option (b) is the correct answer.

Explanation:

When an atom shares electrons with another atom then it results in the formation of covalent bond.

Whereas when an atom transfer electrons from one atom to another then it results in the formation of ionic bond.

When nucleus of an atom splits then it represents nuclear fission reaction and energy is released during this process.

For example,

Therefore, we can conclude that out of the given options, the nucleus of an atom is split apart most likely release the greatest amount of energy.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
