Xenon

Xenon (Xe) is one of six noble gases. It is sometimes used in lighting, such as special flashlight bulbs.

770 Questions

Why does xenon not combine readily with other elements?

Elements have a number of electrons in their outer shell of the atom, all elements want to have a full shell and usually form with other atoms to do so. However, Xenon is a noble gas and already has a full outer shell and so does not combine with other elements unless it is made to do so.

What happens when fluorine reacts with xenon?

When fluorine reacts with xenon, xenon hexafluoride (XeF6) is formed. This is a colorless, crystalline solid that is highly reactive and can even react with glass. The reaction between fluorine and xenon is exothermic and requires controlled conditions due to the extreme reactivity of fluorine gas.

Is xenon dioxide ionic or covalent?

Xenon dioxide is covalent. Xenon has a tendency to form covalent compounds due to its high electronegativity and full valence shell. In xenon dioxide, xenon shares electrons with oxygen atoms to form covalent bonds.

What is the configuration of xenon?

The atomic number of xenon is 54. It has 54 electrons and its electronic configuration is 2, 8, 18, 18, 8 or [Kr] 5s2 4d10 5p6

What is the symbol and number of electrons in a neutral atom of xenon?

The symbol for xenon is Xe, and a neutral atom of xenon has 54 electrons.

What is the group and period of xenon?

Xenon is a noble gas. It belongs to group 18 and period 5.

Are there any other isotopes of xenon?

Xenon has eight stable naturally occuring isotopes. Besides these stable forms, there are over 40 unstable isotopes that have been studied.

What is true about one mole of argon and one mole of xenon if both are present at the same temperature and pressure?

At temperatures at which both elements are gases, they occupy equal volumes, since both are almost perfectly "ideal" gases (unless the temperature is so low that the xenon is near its boiling point.)

How do you calculate xenon neutrons?

Xenon has a variety of isotopes, each with a different number of neutrons. The most common isotope, Xenon-132, has 77 neutrons. To calculate the number of neutrons in a xenon isotope, subtract the number of protons (which is equal to the atomic number) from the mass number of the isotope.

What is the mass of a single atom of xenon in amu?

The atomic mass unit (amu) is a unit of mass used to express atomic and molecular weights. The atomic mass of a single atom of xenon is approximately 131.29 amu.

What is configuration of xenon?

Xenon has 54 protons or 54 electrons.

Its electronic configuration is Kr] 5s2 4d10 5p6 or 2, 8, 18, 18, 8

How many xenon atoms are in 10.0 liters of Xe gas at STP?

At STP (standard temperature and pressure), 1 mole of any gas occupies 22.4 liters. 10.0 liters of Xe gas at STP would therefore contain 10.0/22.4 = 0.4464 moles of Xe. 1 mole of Xe contains 6.022 x 10^23 atoms. Therefore, 10.0 liters of Xe gas at STP would contain 0.4464 x 6.022 x 10^23 = 2.69 x 10^23 xenon atoms.

What compounds can xenon form?

Xenon can form compounds with elements such as fluorine, oxygen, and chlorine. Some common xenon compounds include xenon tetrafluoride (XeF4), xenon hexafluoride (XeF6), xenon difluoride (XeF2), xenon trioxide (XeO3), and xenon tetroxide (XeO4).

Is Xenon a cation?

Xenon is not typically a cation. It is a noble gas and typically exists as uncharged atoms in its elemental form. However, xenon can form cations under certain conditions, such as in xenon fluorides.

Is Xenon a anion?

No. Xenon is a neutral element. It has completely filled valence orbitals, hence is stable. It does not form anion.

Does xenon have five energy levels?

No, xenon has multiple energy levels due to its electron configuration. Xenon has a total of 54 electrons, which occupy different energy levels within the atom. It is a noble gas with a full outer shell of electrons, leading to a stable configuration.

Why xenon has high polarising power?

Xenon has high polarizing power because it has a large electron cloud with high electron density, allowing it to induce polarization in nearby molecules or ions more effectively. This is due to xenon's ability to easily distort its electron cloud in response to an external electric field, giving it a strong tendency to interact with other species through induced dipole interactions.

How many outer-orbital electrons are found in an atom of Xenon?

Xenon is found in group 18. It has an electronic configuration of 2, 8, 18, 18, 8 and has eight valence electrons (or eight electrons in the outer most orbital).

Is xenon a conductor?

No, xenon is not a conductor of electricity. It is a noble gas and does not readily conduct electricity under normal conditions.

Why xenon will form compound and neon will not?

Xenon can form compounds because it can expand its valence shell and participate in chemical reactions to achieve a stable electron configuration, known as the "octet rule." Neon, on the other hand, already has a full valence shell with eight electrons, making it highly stable and unreactive.

What type of bond in Solid xenon?

Solid xenon forms van der Waals bonds due to the weak attraction between its atoms. These bonds are formed by temporary dipoles that result from the unequal distribution of electrons around the xenon atoms.

What state is the element xenon in at 20 degrees Celsius?

At 20 degrees Celsius, xenon is in a gaseous state. Xenon is a noble gas that exists as a gas at room temperature and pressure.

Which xenon fluoride contains the greatest percentage of fluoride XeF2 or XeF4 or XeF6?

XeF6 contains the greatest percentage of fluoride among those options, with 6 fluorine atoms per xenon atom. XeF4 has 4 fluorine atoms and XeF2 has 2 fluorine atoms for each xenon atom.

What element has the English name xenon?

Xenon is a chemical element with the atomic number 54 and the symbol Xe. It is a colorless, odorless noble gas found in trace amounts in Earth's atmosphere.
