Ответ:

Держи

Объяснение:

Благородные газы  — группа химических элементов со схожими свойствами: при нормальных условиях они представляют собой одноатомные газы без цвета, запаха и вкуса с очень низкой химической реактивностью[en]. К благородным газам относятся гелий (He), неон (Ne), аргон (Ar), криптон (Kr), ксенон (Xe) и радиоактивный радон (Rn).

Blagorodnye Gases: Definition and Representatives

Blagorodnye gases, also known as noble gases, are a group of chemical elements that are characterized by their low reactivity and stability. The noble gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).

These gases are called "noble" because they were once believed to be too stable and unreactive to form compounds. However, it is now known that under certain conditions, noble gases can form compounds, although they are generally less reactive compared to other elements.

Noble gases have a full complement of electrons in their outermost energy level, making them highly stable. This stability is due to the fact that their outermost energy level is completely filled with electrons, which makes them less likely to gain or lose electrons to form compounds.

The noble gases are colorless, odorless, and tasteless. They are present in the Earth's atmosphere in small amounts. Helium, for example, is the second most abundant element in the universe, but it is relatively rare on Earth. Neon, argon, and other noble gases are also present in the atmosphere, albeit in much smaller quantities.

Noble gases have various applications in different fields. For example, helium is commonly used in balloons, airships, and as a coolant in certain scientific and medical equipment. Neon is used in neon signs, while argon is used in light bulbs and as a shielding gas in welding. Krypton and xenon have applications in lighting, lasers, and as insulating gases in windows.

In conclusion, blagorodnye gases, or noble gases, are a group of chemical elements known for their low reactivity and stability. They include helium, neon, argon, krypton, xenon, and radon. These gases have various applications in different industries and are present in small amounts in the Earth's atmosphere
