Chemical reactions often involve color changes, temperature changes, gas evolution, or precipitate formation. Simple examples of everyday reactions are digestion, combustion, and cooking. As the name suggests, simple reactants produce or synthesize more complex products. The basic form of a synthetic reaction is A + B → AB. A simple example of a synthetic reaction is the formation of water from its elements hydrogen and oxygen: 2 H2(g) + O2(g) → 2 H2O(g).

A physical reaction is a reaction in which a change in the physical properties of matter or substances occurs. Physical properties include density, mass, and volume. The definition of a physical reaction is a reaction in which molecules undergo molecular rearrangements but do not change chemically.

These models show the electron structures of two different nonmetal elements. Element 1 at left has a purple circle at center wi
Daniel [21]

Answer:

Element 2

Explanation:

If we look at the model stated for element 1, it is clear that element 1 must be a noble gas. It has eight electrons in its outermost shell this implies that it has already attained a complete octet of electrons and is reluctant towards chemical reaction.

The second element belongs to group 16 since it has six electrons on its outermost shell. It is certainly more reactive than element 1 which is a noble gas.
