Noble Gases

Helium is most commonly found in the Earth's crust, often in natural gas deposits. It can also be found in the atmosphere in small amounts. Helium is not typically found in significant quantities in the oceans.

Yes, the electron structure of a zinc ion (Zn2+) achieves a pseudo noble gas configuration by losing two electrons to have a full outer shell, similar to a noble gas configuration. This stable electron configuration is in line with the octet rule, making it an example of pseudo noble gas formation.

The element is magnesium with an atomic number 12.The element belongs to the 3rd period, with two valence electrons in the s orbitals. The element is an example of alkaline earth elements or group 2 elements.

Moroccan argan oil is known for its benefits for skin and hair. It is rich in essential fatty acids and antioxidants, which can help moisturize, nourish, and repair skin and hair. It can also help reduce inflammation and promote a healthy scalp and hair growth.

Argon is a noble gas and is typically unreactive, so it does not form many compounds under normal conditions. However, argon can form stable compounds with fluorine, such as argon fluorohydride (HArF), under extreme conditions. These compounds are usually only observed in laboratory settings or under high pressure conditions.

Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration. Hence they are chemically inert and generally do not form compounds under normal conditions.

No, magnesium and argon cannot form a compound as they are both noble gases and do not readily react with other elements to form compounds. Magnesium is a metal and tends to form ionic compounds, while argon is a noble gas and exists as single atoms due to its stable electronic configuration.

To achieve a noble gas configuration, nitrogen needs to gain three electrons to have a completely filled outer shell like neon. This would give it a charge of -3 since each gained electron carries a negative charge.

NEON is a gas that is colorless, odorless, and inert. It is commonly used in neon signs to create a bright orange-red glow when electricity passes through it.

Argon is isoelectronic with the sulfide ion.

Two hydrogen atoms can be combined through a nuclear fusion process to form a helium atom. This fusion process involves the two hydrogen atoms combining their nuclei to form a helium nucleus, releasing a large amount of energy in the process. This reaction is the core process that powers the sun and other stars.

Helium is located on the group 18 and period 1 on the modern periodic table.

Helium is a chemical element that exists in a gaseous state at room temperature and pressure. It is one of the few elements that remains a gas under normal conditions, even at very low temperatures.

Helium is lighter than air. So it will float in air.

Except for helium, whose valence configuration is 1s2, the valence configuration for the rest of the noble gases consists of the highest energy level s2p6 configuration, for a total of 8 valence electrons. The highest energy level corresponds to the row number on the periodic table. So, radon, at the end of row six, has a valence configuration of 6s26p6.

The sun in composed of 25 percent helium. The other 75 percent is hydrogen. The sun also has small amounts of other elements such as neon, oxygen, carbon, and magnesium.

Argon is found in Group 18 of the periodic table, which is known as the noble gases. Argon is a colorless, odorless, and inert gas that is commonly used in various applications, such as welding and lighting.

Helium does not have a luster because it is a noble gas.

As you go down the group of noble gases, the boiling points generally increase. This is due to the increase in molecular weight and London dispersion forces between the heavier atoms. Helium has the lowest boiling point, while radon has the highest boiling point among the noble gases.

Yes. The ion Ca2+ and the element argon, have 18 electrons each.

1. Helium is an inert gas, meaning it is very unreactive and does not easily form compounds with other elements.
2. It has a very low boiling and melting point, making it useful for cryogenic applications.
3. Helium is less dense than air, which is why it is commonly used to fill balloons and airships.
4. It has a high thermal conductivity, making it useful in cooling applications.
5. Helium is non-toxic and does not support combustion, making it a safe choice for a variety of industrial uses.

No. Helium is a noble gas and has a full compliment of electrons in the first 'orbit' of its atoms. This makes it very, very stable and inert. Therefore helium forms no compounds with any other element. As burning in air by definition is the reaction between the substance and oxygen in the air to form an oxide (e.g. charcoal (carbon) burns in air on your barbecue to form carbon dioxide), as helium will not react with oxygen it will not burn. Helium is also lighter than air. Therefore, helium is sometimes used to fill airships to provide a lift. Airships were once filled with hydrogen as hydrogen is also lighter than air, but several disasters happened where the airship caught fire killing the occupants inside- as hydrogen reacts well with the oxygen in the air (even explosively) form hydrogen oxide (water vapour). As helium is so inert,. it is very useful AND safe for such a use nowadays.

Argon is a non-combustible gas because it is inert and does not readily participate in chemical reactions. It is used in fire suppression systems to displace oxygen and prevent combustion.

Helium is a gas and will take the shape of the container it is taken
