How many protons, neutrons and electrons does Argon have? - 3377908 18 + N = 40. 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). This tells you that it has 18 protons. the mass is made up of both protons and neutrons... therefore 40 - 18 = # neutrons. (Use your periodic table.) The protons and electrons cancel each other out because protons produce a positive charge, electrons a negative charge, and they have the same amount. Argon has 22 neutrons in its nucleus, and the atomic weight of argon is 39.948 atomic mass units. In writing the electron configuration for Argon the first two electrons will go in the 1s orbital. 18. What element has 20 protons? anon138682 January 2, 2011 . (Isotopes of an element have varying numbers of neutrons in the nucleus.) Answer (1 of 4): 18 protons, 18 electrons, and 22 protons. How many protons neutrons and electrons does argon have? anon112516 September 20, 2010 . Argon has an atomic number of 18 and and Atomic mass of 40. 900 seconds . 5 years ago. SURVEY . anon110827 September 13, 2010 When we write the configuration we'll put all 18 electrons in orbitals around the nucleus of the Argon atom. The number of protons is what defines the element. If an element has 83 protons, what is its atomic number and which element is it? How many neutrons and electrons does argon have? Argon was discovered by Sir William Ramsay in 1894. 22. Argon (Ar) atom Bohr model video using the Periodic Table to determine the number of Protons, neutrons, the Atomic Mass, Atomic Number, number . N = 22. there are 22 neutrons. Atomic number 83 and its identity is Bismuth. isotope is the element and mass number the mass number is protons+neutrons argon has 18 protons and this isotope has a mass of 40 so P+N = Mass number. What common compounds does Argon form? Your welcome! An atom of argon has 18 protons and 22 neutrons. in what field does argon belong? It is a nonmetal and a gas at room temperature. :) … anon252703 22 hours ago . Potassium (K) Calcium (Ca) Nitrogen (N) Neon (Ne) Tags: Question 25 . 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. There are 22 neutrons in one atom of argon. It is a noble gas and belongs to period 3 and group 18 of the periodic table. 40. Because its outer electron shell is full, it is chemically unreactive. On the periodic table, argon's atomic number is 18. 18 protons, 18 electrons, 40-18=22 neutrons. Therefore, argon has no electric charge (as with other elements). 1 1.
