Krypton is a non-toxic (non-poisonous) gas that makes up 1 ppm (part per million) of the atmosphere. It does not react easily with anything and has practically no effect on the environment.
aA change that makes you react is called a sensory feeling
Such substances are semi-metals as Zn,Sn and Al , and their oxides, such substances are known as Amphoteric.
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.
No. Cesium reacts with a number of nonmetals, bu not with other metals or metalloids. Cesium is a powerful reducing agent and will react strongly with oxidizing substances.

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.
Krypton is a non-toxic (non-poisonous) gas that makes up 1 ppm (part per million) of the atmosphere. It does not react easily with anything and has practically no effect on the environment.
Chemical
reactivity
This is how they react to the substances. Sometimes the substances that are inside the plant will react in an unusual way with the substance.
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.
