A reaction, such as this one, starts with a reactant. It needs to have activation energy in order to change to the product, as shown by the hump in the graph. At the top of the hump is the transition state. This is the point where, after enough energy, the reactant will turn into the product. This reaction is exothermic. Since the product has less energy than the reactant, it had to have released energy somehow, and that energy was released in the form of heat, which makes it exothermic. (Exothermic reactions release heat, vs. endothermic reactions which absorb heat).

Bonus: a catalyst can be used to lower the activation energy by giving the reaction a “kick start,” requiring less energy in the reaction for the reactant to turn into the product.

Answer from: Quest

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is $1s^{2}2s^{2}2p^{6}3s^{1}$ and electronic configuration of phosphorous is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{3}$ .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

$3na + p \rightarrow na_{3}p$

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

Electrons are transferred from atoms of to atoms of this transfer makes the sodium atoms and the
