Calculate (A) the number of electrons (B) number of protons (C) number of neutrons(D) mass number. Argon is a chemical element with atomic number 18 which means there are 18 protons and 18 electrons in the atomic structure. Argon is the third-most abundant gas in the Earth’s atmosphere, at 0.934% (9340 ppmv). So, it has 3 electron shells, and that will be its valence shell. You must recognize that the second principal energy level consists of both the \(2s\) and the \(2p\) sublevels and so the answer is three. The protons and electrons cancel each other out because protons produce a positive charge, electrons a negative charge, and they have the same amount. In the third shell, it holds a total of 2+6=8 electrons, so it has 8 valence electrons. You'll also have 83 argon atoms, and 667 calcium atoms. 3 B. Electrons are particles that have a negative charge equal to -1. How many valence electrons does argon have? Next element of the periodic table. Since the outer shell electrons are fully filled, argon have no tendency to gain nor lose electrons. How many valence electrons does nitrogen have? Rate! Thanks Comments; Report Log in to add a comment Looking for something else? Because the third energy level has eight electrons and is therefore full (3s 2 3p 6) it is called a noble gas. argon has … Therefore the Argon electron configuration will be 1s 2 2s 2 2p 6 3s 2 3p 6. 5.0 1 vote 1 vote Rate! 5 years ago . * Electron configuration: [Ne] 3(s(2)) 3(p(6)). Hence, we can say that both are isoelectronic, having the same of number of neutrons. This full valence shell makes argon very stable and extremely resistant to bonding with other elements. You have 1 free answer left. 0 0. 8 Argon is a noble gas with an electron configuration of [Ne]3s^2\\3p^6. Nitrogen makes up DNA both in the form of nitrogen bases and in neurotransmitters. Find more answers . It has five electrons in its outer shell, most of its compounds are trivalent. Your welcome! Source(s): protons element argon have: https://shortly.im/cnfo3. All noble gases have p orbitals (and energy layers) full of electrons. It can have either 3 or 5 valence electrons, as it can bond in the 2p and 2s orbitals outside. Explain that argon has 18 protons and 18 electrons. Ask your question. The number of protons of an atom cannot change via any chemical reaction, so you add or subtract electrons to get the correct charge. Get an answer. The electron configuration for Ca 2+ is the same as that for Argon, which has 18 electrons. Ti First, we see that the electron configuration is made of the core electrons (Ar) and the valence electrons (4s23d2). For example, boron (B) has an atomic number of 5, therefore it has 5 protons and 5 electrons. 40-18 is 22. We are suppose to do:-An isotope of that atom-An ion of that atom, with a positive charge. Rather like a puzzle box containing exactly the right number of pieces, argon and its five cousins does not have any subatomic shortages that need to be amended by donations from other elements, and it doesn't have any extras floating around to donate in turn. Chlorine is before argon on the periodic table, so it does not have all the electrons argon has in its ground state. Wait, I am looking it up in a reference. 1 See answer pi5lbibaysSwimg is waiting for your help.
