Argon has a Heat of Vaporization of 6.447 kJ/mol. Argon (18 Ar) has 26 known isotopes, from 29 Ar to 54 Ar and 1 isomer (32m 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. The longest-lived radioactive isotopes are 39 Ar with a half-life of 269 years, 42 Ar with a half-life of 32.9 years, and 37 Ar with a half-life 2018-10-17 · Fast Facts: Argon Element Name: Argon Element Symbol: Ar Atomic Number: 18 Atomic Weight: 39.948 Appearance: Colorless inert gas Group: Group 18 (Noble Gas) Period: Period 3 Discovery: Lord Rayleigh and William Ramsay (1894) Atomic Number of Argon Argon is a chemical element with atomic number 18 which means there are 18 protons and 18 electrons in the atomic structure. The chemical symbol for Argon is Ar. Atomic Mass of Argon Atomic mass of Argon is 39.948 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element.

Reveal answer. Number of protons = 17. Therefore the atomic mass of hydrogen is 1.00784 amu. The atomic mass of an element element is measured in atomic mass unit (amu, also known as Daltons ‘ D’or unified atomic mass unit ‘u’). 1amu = 1.66 x 10-24 grams. 1gm = 6.022 x 10 23 amu ( i.e. Avogadro’s number).
