It is a nonmetal and a gas at room temperature. Argon has an atomic number of 18 and and Atomic mass of 40. 1 1. There are 22 neutrons in one atom of argon. 4. How many electrons does it have? Therefore, argon has no electric charge (as with other elements). This tells you that it has 18 protons. The number of protons is what defines the element. Please answer me asap! How many neutrons and electrons does argon have? Argon was discovered by Sir William Ramsay in 1894. The protons and electrons cancel each other out because protons produce a positive charge, electrons a negative charge, and they have the same amount. SURVEY . Atomic number 83 and its identity is Bismuth. 40. 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. 18. It is a noble gas and belongs to period 3 and group 18 of the periodic table. 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. Because its outer electron shell is full, it is chemically unreactive. In writing the electron configuration for Argon the first two electrons will go in the 1s orbital. What element has 20 protons? 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 Tags: Question 24 . N = 22. there are 22 neutrons. :) … If an element has 83 protons, what is its atomic number and which element is it? argon has a molar mass of 40 and 18 prontons. anon110827 September 13, 2010 900 seconds . 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). How many protons, neutrons and electrons does Argon have? How many protons neutrons and electrons does argon have? is argon used in light bulbs? (Isotopes of an element have varying numbers of neutrons in the nucleus.) in what field does argon belong? anon112516 September 20, 2010 . Your welcome! argon has 22 neutrons the mass is made up of both protons and neutrons... therefore 40 - 18 = # neutrons. When we write the configuration we'll put all 18 electrons in orbitals around the nucleus of the Argon atom. 18 + N = 40. Potassium (K) Calcium (Ca) Nitrogen (N) Neon (Ne) Tags: Question 25 . An atom of argon has 18 protons and 22 neutrons. Answer (1 of 4): 18 protons, 18 electrons, and 22 protons. What common compounds does Argon form?
