What element has 20 protons? argon has 22 neutrons anon138682 January 2, 2011 . (Use your periodic table.) Anonymous. 4. :) … An atom of argon has 18 protons and 22 neutrons. If an element has 83 protons, what is its atomic number and which element is it? 18 protons, 18 electrons, 40-18=22 neutrons. is argon used in light bulbs? SURVEY . Atomic number is the number of protons. 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. in what field does argon belong? anon252703 22 hours ago . 40. 900 seconds . On the periodic table, argon's atomic number is 18. Argon was discovered by Sir William Ramsay in 1894. (Isotopes of an element have varying numbers of neutrons in the nucleus.) This tells you that it has 18 protons. Answer (1 of 4): 18 protons, 18 electrons, and 22 protons. N = 22. there are 22 neutrons. anon110827 September 13, 2010 5 years ago. Name: Argon Symbol: Ar Atomic Number: 18 Atomic Mass: 39.948 amu Melting Point:-189.3 °C (83.85 K, -308.74 °F) Boiling Point:-186.0 °C (87.15 K, -302.8 °F) Number of Protons/Electrons: 18 Number of Neutrons: 22 Classification: Noble Gas Crystal Structure: Cubic Density @ 293 K: 1.784 g/cm 3 Color: Colorless Gas Atomic Structure The number of protons is what defines the element. It is a noble gas and belongs to period 3 and group 18 of the 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. It is a nonmetal and a gas at room temperature. How many electrons does it have? In writing the electron configuration for Argon the first two electrons will go in the 1s orbital. When we write the configuration we'll put all 18 electrons in orbitals around the nucleus of the Argon atom. Tags: Question 24 . Atomic number 83 and its identity is Bismuth. Because its outer electron shell is full, it is chemically unreactive. How many protons, neutrons and electrons does Argon have? How many neutrons and electrons does argon have? Argon has an atomic number of 18 and and Atomic mass of 40. 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. 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. Therefore, argon has no electric charge (as with other elements). Argon has 22 neutrons in its nucleus, and the atomic weight of argon is 39.948 atomic mass units. What common compounds does Argon form? 18. Your welcome! Please answer me asap! 1 1. - 3377908 Potassium (K) Calcium (Ca) Nitrogen (N) Neon (Ne) Tags: Question 25 .
