Krypton is a rare and inert gas that does not react significantly with the environment. It is considered non-toxic and has no known adverse effects on ecosystems or human health. However, it does contribute to the greenhouse effect when present in the atmosphere, although its concentration is very low compared to other greenhouse gases.
Fluorine is extremely reactive. It will react with many substances at room temperature and can spontaneously set fire to organic material. It will react exothermically with substances normally used to extinguish fires such as water and carbon dioxide. When it reacts it can form toxic compounds such as hydrogen fluoride.
Helium does not react with other elements. It is a noble gas and has a full outer shell of electrons. Because it is not seeking to gain or lose any of its electrons, it will not react.
The ability of an element to react is determined by its reactivity, which is its tendency to undergo chemical reactions with other substances. Elements with high reactivity easily form compounds, while elements with low reactivity are less likely to react with other substances. Reactivity is influenced by factors such as the number of electrons in the outermost energy level of the atom.
Iodine does not react with baby powder. Baby powder is usually made of talc or cornstarch, which are inert substances and do not participate in chemical reactions with iodine.

CFC's are ozone depletion substances. They react with ozone and deplete it.
CFC's are man made ozone depleting substances. They react with ozone and deplete it.
when two substances react a chemical change occurs
The ability to react with other substances is a chemical property.

It's the other way around. Senses - sight, hearing, smell, taste, touch - react to things and changes in the environment.
Xenon does not have any particular effect for two reasons:it is inert so does not easily react with other substances,it accounts for 1 part in 10 million (0.00001%) of the Earth's atmosphere.
No, helium is not a cause of global warming. Helium is an inert gas and does not react with other substances in the atmosphere to contribute to the greenhouse effect.
