Why is xeon the only gas in the periodic table beginning with x?

Xenon is the only gas in the periodic table that begins with the letter "X" because it is the only element with a name that starts with that letter. The names of elements are derived from various sources including Latin and Greek, and "xenon" comes from the Greek word for "stranger" or "foreigner."


If the density of a noble gas id 1.783 gL at STP that gas is?

1.783 grams/liter x 22.4 liters/mole = 40 grams/mole = Argon


If X is in period 5 the ion formed has the same electron configuration as the noble gas?

If element X is in period 5 of the periodic table, it typically has five electron shells. When it forms an ion, it often loses or gains electrons to achieve a stable electron configuration similar to that of the nearest noble gas, which in this case is krypton (Kr). For example, if X is a metal, it may lose electrons to form a cation with a configuration resembling Kr. Conversely, if X is a non-metal, it may gain electrons to achieve the same stable electron configuration.


How might you use an unreactive nonmetal gas?

Nonreactive gases (or noble gases) are often used as a shielding gas to prevent atmospheric contamination, or as an insulator in high voltage circuitry. They are also often used to modulate wave frequencies for anything from light to radar to X-rays.


General electronic configuration of group having low ionisation energy?

The general electron configuration of the group having the lowest ionization energy is [Noble gas configuration]xs1. In this case, x is the principal quantum number of the valance electron. The noble gas configuration may either be written out in full or denoted by the noble gas' atomic symbol in brackets (ie [Ne]).
