how many neutrons does argon have

argon has a molar mass of 40 and 18 prontons. This means that some Argon atoms have 18 neutrons, some 20 neutrons and some 22 neutrons the isotope with 22 neutrons is the most common and forms 99.6% of all Argon. answer choices . Therefore, argon has no electric charge (as with other elements). anon138682 January 2, 2011 . What common compounds does Argon form? How many protons, neutrons and electrons does Argon have? Anonymous. argon has 22 neutrons - 3377908 Atomic number is the number of protons. Argon has an atomic number of 18 and and Atomic mass of 40. On the periodic table, argon's atomic number is 18. When we write the configuration we'll put all 18 electrons in orbitals around the nucleus of the Argon atom. If an element has 83 protons, what is its atomic number and which element is it? Atomic number 83 and its identity is Bismuth. Because its outer electron shell is full, it is chemically unreactive. In order to write the Argon electron configuration we first need to know the number of electrons for the Ar atom (there are 18 electrons). There are 22 neutrons in one atom of argon. The protons and electrons cancel each other out because protons produce a positive charge, electrons a negative charge, and they have the same amount. Tags: Question 24 .
