Krypton (Kr) is a noble gas found in the air. It has limited its practical applications, but never the less, Krypton is used in some types of photographic flashes used in high speed Photography. Some fluorescent light bulbs are also filled with a mixture of krypton and argon gases. Krypton gas is also combined with other gases to make luminous signs that glow with a greenish-yellow light.

Where do you bump into krypton in every day life and what form is it in?

Krypton is a rare and inert gas that is typically found in trace amounts in the Earth's atmosphere. It is used in certain types of lighting, such as fluorescent lights and some high-intensity discharge lamps. In everyday life, you may come across krypton in these lighting applications.


What is the half life of krypton 92?

The half-life of krypton-92 is approximately 2.5 hours. This isotope of krypton is radioactive and decays primarily through beta decay into rubidium-92. Its relatively short half-life makes it useful in various applications, including nuclear medicine and research.


How do you find the atomic mass for the element krypton?

To find the atomic mass of krypton, you can add up the number of protons and neutrons in its nucleus. Krypton has an atomic number of 36, which means it has 36 protons. You can find the atomic mass on the periodic table, which is usually around 83.798 u for krypton.


What is the mass of 5.00 mol of krypton in grams?

To find the mass of 5.00 moles of krypton (Kr), you multiply the number of moles by the molar mass of krypton. The molar mass of krypton is approximately 83.80 g/mol. Therefore, the mass of 5.00 mol of krypton is 5.00 mol × 83.80 g/mol = 419.00 grams.


How many moles are contained in 1.23 grams of krypton?

To determine the number of moles in 1.23 grams of krypton, first find the molar mass of krypton (Kr), which is approximately 83.80 g/mol. Then, divide the given mass (1.23 g) by the molar mass of krypton to find the number of moles. In this case, 1.23 g / 83.80 g/mol ≈ 0.015 moles of krypton.
