Since it has 7 electrons in its outer-most shell, it needs one more electron to achieve stability or the octet state. 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. 11) When a cation is formed from a representative element _____. 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. The number of neutrons is calculated by subtracting the atomic number from the mass number. Electronic distribution of Chlorine is as follow:Cl - 17= 2,8,7It has 2 electrons in K shell, 8 in L and 7 in My shell.EmoLord. Chlorine (Cl) has nine electrons. Determine the electron geometry and explain your... Who is credited with measuring the mass/charge... What is the total number of outer (valence)... What is the valence electron configuration for the... A hydrogen atom has one electron. 77 terms. This formation makes chlorine very reactive, as all atoms want full outer shells with 8 electrons. The atomic number of chlorine is 17. All other trademarks and copyrights are the property of their respective owners. How many electrons are in the highest occupied energy level of a neutral chlorine atom? 1 1. With two oppositely charged ions, there is an electrostatic attraction between them because opposite charges attract. An elements has an atomic number 17.How many electrons are present in K,L and M shell of an atom - 30417991 A chlorine atom has 7 electrons in its outer shell. 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 … - Definition & Equation, Electron Orbital: Definition, Shells & Shapes, The Activity Series: Predicting Products of Single Displacement Reactions, States of Matter: Solids, Liquids, Gases & Plasma, Monatomic Ions: Definition & Naming Convention, Representative Elements of the Periodic Table: Definition & Overview, CLEP Natural Sciences: Study Guide & Test Prep, Middle School Life Science: Tutoring Solution, Holt McDougal Modern Chemistry: Online Textbook Help, Praxis Chemistry (5245): Practice & Study Guide, College Chemistry: Homework Help Resource, CSET Science Subtest II Chemistry (218): Practice & Study Guide, ISEB Common Entrance Exam at 13+ Geography: Study Guide & Test Prep, Holt Science Spectrum - Physical Science with Earth and Space Science: Online Textbook Help, Biological and Biomedical The chemical element chlorine has 17 electrons, 17 protons and 18 neutrons. This is a special case, where chlorine is the central atom, but remember that fluorine usually has one bond and three lone pairs. These elements when combining with the more electronegative element, their electrons of nth orbit get promoted to n-‘d’ orbital. This answer has been viewed 111 times yesterday and 358 times during the last 30 days. 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. Services, Valence Electrons and Energy Levels of Atoms of Elements, Working Scholars® Bringing Tuition-Free College to the Community. 17 Arrange electrons until both nitrogen and fluorine get 8 electrons. The number of neutrons is calculated by subtracting the atomic number from the mass number. 7. In the atom of an element X, 6 electrons are present in the outermost shell. how many electrons are in chlorine is one of the most frequently asked questions. In many cases, elements that belong to the same group (vertical column) on the periodic table form ions with the same charge because they have the same number of valence … Total valence electrons given by chlorine atoms = 7*1 = 7 There are three oxygen atoms in ClO 4- ion, Therefore On the right, the chloride ion has 18 electrons and has a 1− charge. How many... How many inner/core and outer/valence electrons... Where do the negative subatomic particles... How is atomic number related to core electrons? C) lose 7 4. Alex G. asked • 08/27/19 An atom of chlorine has an atomic number of 17 and a mass number of 37. Protons have a +1 charge and electrons have a -1 charge. Create your account. 10) How many electrons will chlorine gain or lose when it forms an ion? Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and seven in shell three. Chlorine Compound of the Month: 8661 Taking Its Place on The Periodic Table .
