A catalytic converter is a device used in automobiles that helps to create less pollution for the environment. To comply with the U. S. Environmental Protection Agency's stricter regulation of exhaust emissions, most gasoline-powered vehicles starting with the 1975 model year must be equipped with catalytic converters.

The image shows a platinum surface inside a catalytic converter and how it causes a chemical reaction. Predict the outcome for the environment if platinum could no longer be used for catalytic converters.

A) Less gas would be produced which would help the automobile stay in good condition for a longer period of time.
B) More carbon dioxide would be available for our plants and trees.
C) More carbon monoxide gas would evolve from exhaust systems in automobiles endangering the environment.
D) Less oxygen would be available for people to breathe causing a problem for the driver and passengers in the vehicle.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
