Noble Gases

Yes, "He" refers to the chemical symbol for the element helium, which is a noble gas. Helium is a colorless, odorless, and non-toxic gas that is commonly used in various applications such as balloons and as a coolant in superconducting magnets.

s orbital for helium and p orbitals for other noble gases.

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.

However noble gases like krypton and xenon will bind with highly electronegative elements like oxygen and fluorine.

Neon is more stable than chlorine because neon is a noble gas with a full outer shell of electrons, making it very unreactive and stable. Chlorine, on the other hand, is a halogen that is highly reactive due to its need to gain one electron to achieve a full outer shell. This reactivity makes chlorine less stable than neon.

Helium was most found in the United States in natural gas reserves in Amarillo Texas. The government stockpiled it during the cold war and they are now selling it for a ridiculously low price.

No, helium can escape through the microscopic pores in copper pipe due to its small molecular size. It is not an effective choice for helium containment. Stainless steel or specialized materials are typically used for helium gas containment.

Electron Configuration for Mg: 1s2 2s2 2p6 3s2

Noble Gas Notation for Mg: [Mg] 3s2

Yes, its to do with the gas density difference of air and helium, rather than the density of gas due to temperature.

2 electrons in the K shell and 8 electrons in the L shell

Helium is a noble gas and does not readily form compounds with other elements because it has a full outer shell of electrons, making it very stable and unreactive. Additionally, helium has a very low electron affinity and electronegativity, further limiting its ability to form chemical bonds with other elements.

Helium at room temperature is commonly used to inflate balloons due to its low density, making balloons float.

If by octect you mean the outermost shell, then yes.. that's why they're noble gasses (inert)

Yes. On the periodic table, it is labeled under the noble gases because all of its energy shells of electrons are completely filled up to make it unreactive like the other noble gases, helium, neon, argon, krypton, xenon, and radon.

A very good conductor.

A step-by-step instructional format with clear headings and bullet points would be best suited for writing directions for constructing a functional helium balloon. This format allows for easy readability and understanding, guiding the reader through each stage of the construction process. Additionally, including visual aids such as diagrams or images can further enhance the clarity of the instructions.

Other elements can acquire a noble gas configuration by gaining or losing electrons to achieve a full outer electron shell, similar to that of a noble gas. This can be done through forming chemical bonds with other elements or ions in order to stabilize their electron configuration.

Nitrogen has the greatest electronegativity among xenon, nitrogen, and lithium. Electronegativity is a measure of an element's ability to attract electrons in a chemical bond, with nitrogen having a value of 3.04 on the Pauling scale, which is higher than xenon (2.60) and lithium (0.98).

Atoms attain stable configuration of noble gas by gaining or losing electrons to achieve a full outer electron shell, often referred to as an octet. This stable arrangement mimics the electron configuration of noble gases and provides the atom with increased stability and lower energy. This can be achieved through ionization (loss or gain of electrons) or bonding with other atoms to share electrons.

They both are non metals. there is no other similarities.

argon forms a fairly considerable part (0.94% by volume, 1.3% by mass) of the Earth's atmosphere

Helium is a noble gas and is inert, meaning it does not react with common compounds like oxygen, nitrogen, or carbon dioxide. Helium is chemically stable and does not form compounds easily due to its full outer electron shell.

No, noble gases are not metals; they are a group of non-metal elements. Noble gases are the least reactive elements because they have a full valence shell of electrons, which makes them stable and unlikely to form chemical bonds with other elements. Alkali metals are the most reactive metals, while transition elements have varying reactivity levels depending on the element.

The noble gasses all have a filled outer electron shell of eight electrons, except helium which has two electrons. Since their outer electron shells are filled, they are less likely to react with other atoms.

Krypton is a noble gas because it has a full valence shell of eight electrons, making it stable and unreactive. It does not readily form chemical bonds with other elements, which is a characteristic of noble gases.

When a lighted splint is put into a glass jar of helium, the splint will immediately extinguish because helium is an inert gas that does not support combustion. The lack of oxygen in the helium prevents the splint from continuing to burn.
