Noble Gases

It is found in group 18 (the group on the extreme right)

Oxygen has a stronger force of attraction compared to helium because oxygen has a higher atomic number and more protons, resulting in stronger electrostatic forces between its nucleus and electrons.

Neon colors became popular in the 1980s, with fluorescent hues dominating the fashion and design trends of the decade. The vibrant and eye-catching nature of neon colors symbolized the bold and vibrant attitude of the 80s.

It is not recommended to mix helium and acetylene as they have different physical and chemical properties. Helium is an inert gas while acetylene is a flammable gas. Mixing them could create a hazardous situation due to the risk of combustion or explosion.

No. Helium is one of the "noble" gasses, and they generally don't react with much.

A helium flash occurs in low-mass stars during the helium burning phase. High-mass stars do not experience a helium flash because they have a higher core temperature and pressure, so helium burning begins smoothly without the need for a sudden ignition event. Additionally, high-mass stars have higher energy production rates, which prevent the conditions required for a helium flash from occurring.

Noble gases like helium, xenon, and argon are being researched for their potential therapeutic applications in cancer treatment. Helium is commonly used for cooling during surgeries, xenon is being studied for its neuroprotective properties, and argon is being investigated for its potential to induce cancer cell death.

Argon is more abundant in the Earth's atmosphere compared to other noble gases, which makes it easier and cheaper to extract. Additionally, the extraction process for argon is simpler and more efficient than for other noble gases, contributing to its lower production cost.

Helium is the noble gas used for cancer treatment. It is used in a technique called Helium Ion Therapy, where helium ions are used to precisely target and treat cancer cells without damaging surrounding healthy tissues.

The noble gases all have full valence electron shells, which makes them very stable and unreactive. Their electron configurations are considered "closed" because they have a complete set of electrons in their outermost energy level or shell. This stability prevents them from forming chemical bonds easily with other elements.

When phosphorus achieves a noble gas configuration, it gains three electrons to become the phosphide ion (P³⁻). This allows it to achieve the stable electron configuration of a noble gas, similar to argon.

There are six noble gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.

Using the ideal gas law equation, PV = nRT, where P is pressure, V is volume, n is number of moles, R is the gas constant, and T is temperature in Kelvin, you can solve for V. Rearranging the equation to solve for V, you get V = (nRT)/P. Plugging in the values n = 0.80 moles, R = 8.31 J/(K*mol), T = 300 K, and P = 204.6 kPa (convert to Pa first), you can calculate the volume needed.

Yes, helium is still commonly used in blimps due to its low density and non-flammable properties, making it a safe option for lifting aircraft. Helium provides the necessary buoyancy to keep blimps afloat and is widely used in the aerospace industry for this purpose.

xenon is a gas at STP

Neon typically forms the neon ion, Ne+. This ion is produced by removing one electron from a neutral neon atom, leaving it with a positive charge.

Helium has a full outer shell of electrons and so is more like the other noble gasses than the other, much more reactive s-orbital elements. With the exception of hydrogen and helium all of the s-orbital elements are metals.

The electron arrangement in a sodium ion (Na+) is similar to neon, as both have a full outer electron shell. Sodium loses one electron to achieve the stable electron configuration of neon (2,8). Argon has a full outer shell with 8 electrons, making it different from both sodium and neon.

Noble gases are found in column (or group) 18

No, neon tetras are freshwater fish and cannot thrive in saltwater. They require specific water conditions and saltwater would be harmful to their health. It is important to provide neon tetras with the proper environment to ensure their well-being.

Noble gasses are different from other elements because they are stable (have either 8 or 0 valence electrons) and do not share, give, or take electrons (do not create bonds with other elements. And, they do not form compounds.

The nuclear process that converts helium and hydrogen into heavier elements is nuclear fusion. In this process, the nuclei of lighter elements combine to form the nuclei of heavier elements, releasing large amounts of energy in the process. This is the process that powers stars like our Sun.

No, nitrous oxide (laughing gas) and helium are not the same thing. Helium is an inert gas commonly used in party balloons and as a cooling agent in various applications, while nitrous oxide is a colorless gas often used as an anesthetic or in whipped cream dispensers.

Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. They will not accept any more electrons and hence they have positive electron affinity.
