What determines the types of chemical reactions that an atom participates in?

The innermost electron shell of an atom can hold up to electrons. ... What determines the types of chemical reactions that an atom participates in? the number of electrons in the outermost electron shell. Atoms with the same number of protons but with different electrical charges

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

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.
