These elements when combining with the more electronegative element, their electrons of nth orbit get promoted to n-‘d’ orbital. So in chlorine, we can see that the atomic number is 17. 1 See answer waz he looks like me thats y you look really cute itisonlyluis is waiting for your help. This makes chlorine's valence shell incomplete, and the atom attracts "loose" electrons to this shell to complete it, so the atom can be stable. Chlorine needs one more elctron to have a full outer shell, so makes it very reactive with other atoms such as lithium, which only … Name the ions present in this compound, KCI. The first electron affinity of chlorine (the energy release when chlorine gains an electron to form Cl −) is 349 kJ per mole of chlorine atoms. The atomic number is the same as the number of protons while the mass number is the sum of the protons and neutrons. 1. How Many Electrons, Protons and Neutrons Does Chlorine Have. 1 (can u see the last one, it's on its own) as for the electron configuration: chlorine has 17 electrons. 77 terms. Since it has 7 electrons in its outer-most shell, it needs one more electron to achieve stability or the octet state. 17 7. Q: In a first-order reaction, the half-life is 133 minutes. The atomic number of chlorine is 17. asked Feb 5, 2018 in Class IX Science by saurav24 Expert (1.4k points) … Chlorine has 17 electrons. That means there are 17 electrons in a chlorine atom. Find 8 answers to How Many Core Electrons Are In A Chlorine Atom? In writing the electron configuration for Chlorine the first two electrons will go in the 1s orbital. Chlorine Compound of the Month: 8661 Taking Its Place on The Periodic Table . According to the modern atomic theory, how many electrons are found in n = 2? Chlorine has an atomic number of 17. An elements has an atomic number 17.How many electrons are present in K,L and M shell of an atom - 30417991 How many electrons are in the highest occupied energy level of a neutral chlorine atom? If chlorine 37 was existing as an ion then it would have 18 electrons. With two oppositely charged ions, there is an electrostatic attraction between them because opposite charges attract. CEO Compensation and America's Growing Economic Divide. The chemical element chlorine has 17 electrons, 17 protons and 18 neutrons. Since the 3s if now full we'll move to the 3p where we'll place the … Chlorine is in group 7 of the periodic table. 1. By adding one more electron we get a negatively charged Cl-ion with a net charge of -1. Create your account. (Atomic number of K=19, CI = 17) Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library. Subtracting 17 from 35 equals 18, which is the number of neutrons in a chlorine atom. 1 answer. The number of neutrons is calculated by subtracting the atomic number from the mass number. E) lose 3 Answer: B Page Ref: 6.1 Learning Obj. As atomic number 17 on the Periodic Table of the Elements, chlorine takes its place between sulfur, atomic number 16, and argon, atomic number 18.Each chlorine atom consists of 17 protons (positively charged sub-atomic particles) in the atom's nucleus (central region), balanced by seventeen electrons (negatively charged sub-atomic … The gain or loss of electrons by an atom to form negative or positive ions has an enormous impact on the chemical and physical properties of the atom. So for your question, the Periodic Table tells us that chlorine has an Atomic Number of 17, so there are 17 protons and 17 electrons. This answer has been viewed 111 times yesterday and 358 times during the last 30 days. In the periodic table, all elements are represented by their chemical symbol with the mass number written on the top-left portion and the atomic number on the bottom-left. We'll put six in the 2p orbital and then put the next two electrons in the 3s. One more electron we get a full outer shells with 8 electrons positive states.
