Which change is most likely to occur when a molecule of H2 and a molecule of I2 collide with proper orientation and sufficient e
bazaltina [42]
The collision of the molecules between the hydrogen molecule or H2, and an iodine molecule or I2, provided there would be a sufficient energy is that the system would eventually undergo a chemical change wherein a new chemical compound would be formed from these two molecules.

Explain how its electron configuration influences the chemical behavior of an atom.
Llana [10]

More unstable an electron configuration , the more reactive an atom will    become.

How electron configuration influences the chemical behavior of an atom?

This is happen generally, If we look at the Group 1 elements in the periodic table, they are all highly reactive as they have 1 electron in their outermost shells - an unstable configuration in terms of energy.

Also, the noble gases in Group 8 in the periodic table are 'inert' that means they don't react (or more correctly, have an incredibly low reactivity). This is because they have 8 electrons in their outermost shell and thus have no need to acquire or lose electrons to possess a stable electron configuration.

Hence, electron configuration influences the chemical behavior of an atom.
