Argon is a chemical element; it has symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. [9] Argon is the third most abundant gas in Earth's atmosphere, at 0.934% (9340 ppmv).
Argon is a chemical element. Its symbol is argon is Ar and its atomic number is 18. It is part of the noble gas group. It is an odorless and tasteless gas. Argon is the third-most abundant gas in the Earth's atmosphere. The name "argon" is from the Greek word ἀργός meaning "lazy" or "inactive" because it does not react with other chemicals.
Argon (18 Ar) has 26 known isotopes, from 29 Ar to 54 Ar, of which three are stable (36 Ar, 38 Ar, and 40 Ar). On the Earth, 40 Ar makes up 99.6% of natural argon.
El argón es un elemento químico de número atómico 18 y símbolo Ar. Es el tercero de los gases nobles, incoloro e inerte como ellos, constituye el 0,934 % del aire seco. Su nombre proviene del griego ἀργός [argos], que significa inactivo (debido a que no reacciona). 1 2 3 4 . Aplicaciones. [editar]
Argon is een scheikundig element met symbool Ar en atoomnummer 18. Het is een kleurloos edelgas. Geschiedenis. In 1785 veronderstelde de Britse wetenschapper Henry Cavendish dat argon in de lucht voor zou moeten komen maar kon dat niet aantonen.
Argon compounds, the chemical compounds that contain the element argon, are rarely encountered due to the inertness of the argon atom. However, compounds of argon have been detected in inert gas matrix isolation, cold gases, and plasmas, and molecular ions containing argon have been made and also detected in space.
Argon–argon (or 40Ar/39Ar) dating is a radiometric dating method invented to supersede potassium–argon (K/Ar) dating in accuracy. The older method required splitting samples into two for separate potassium and argon measurements, while the newer method requires only one rock fragment or mineral grain and uses a single measurement of argon ...
Argon là một nguyên tố hóa học trong bảng tuần hoàn. Nó có ký hiệu Ar và số nguyên tử bằng 18. Là khí hiếm thứ ba trong nhóm 8, argon chiếm khoảng 0,934% khí quyển Trái Đất, điều này làm cho nó trở thành khí hiếm phổ biến nhất trên Trái Đất.
