atomic structure of chlorine atom

Relative atomic mass has no units. the Terms and Conditions. All Rights Reserved. Chlorine is in group 7 of the periodic table. Diagram of the nuclear composition and electron configuration of an atom of chlorine-35 (atomic number: 17), the most common isotope of this element. This is a picture of the shared electrons making a covalent bond in a chlorine molecule. A chlorine atom has more protons in its nucleus than has a sodium atom (1) Both have three shells of electrons (1) Electrons more strongly attracted by chlorine nucleus so size smaller than Na (1) An electron shell is lost when a sodium ion is formed from a sodium atom (1) Inner electrons more strongly attracted so ion smaller than atom (1) Name: Chlorine Symbol: Cl Atomic Number: 17 Atomic Mass: 35.4527 amu Melting Point:-100.98 °C (172.17 K, -149.764 °F) Boiling Point:-34.6 °C (238.55 K, -30.279997 °F) Number of Protons/Electrons: 17 Number of Neutrons: 18 Classification: Halogen Crystal Structure: Orthorhombic Density @ 293 K: 3.214 g/cm 3 Color: green Atomic Structure Every element is unique and has an atomic number.

By sharing this link, I acknowledge that I have read and understand Chlorine is a chemical element with the symbol Cl and atomic number 17. Example Chlorine consists of two isotopes, chlorine – 35 and chlorine – 37 in the ratio 3 : 1. Chlorine is a yellow-green gas at room temperature. How many electrons are there in the L shell? Similarly sulphur (atomic wt. Directions: Under the headings, explain how to obtain each piece of data. Then based on the information given in the row, determine the element and its contents, thus filling out the entire chart.    Other Metals Neutrons = Mass Number - Protons 00:00:44,969 -- 00:00:51,969 When we look at Chlorine on the periodic table it has an atomic number of 17, therefore it 00:00:55,149 -- 00:00:59,860 has 17 protons. So Chlorine-35 has a mass of 35.    Rare Earth Elements, Basic Information | Atomic Structure | Isotopes | Related Links | Citing This Page.    Noble Gases Vital to life in ionic form, chlorine is a halogen in group 17, period 3, and the p-block of the periodic table. In the atom of an element X, 6 electrons are present in the outermost shell. If an atom has 12 protons (atomic number = 12), it must be magnesium. Chlorine (Cl). Every chlorine atom has 17 protons and 17 electrons. In the human body, it's found as the chloride ion, where it … Therefore, the valency of chlorine is often consider… Finally, the outermost electron shell of the chlorine atom (often referred to as the valence shell) contains a total of 7 electrons.    Date of Discovery This page was created by Yinon Bentor. The atomic number of chlorine is 17. The structure of each atoms electrons is unique but there is a pattern. The atomic number of chlorine is 17; thus, it has seventeen protons and seventeen electrons. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally … Number of Energy Levels: 3: First Energy Level: 2: Second Energy Level: 8: Third Energy Level: 7 Calcium is a group II element, but it's metal. Use of this web site is restricted by this site's license The nucleus consists of 17 protons (red) and 18 neutrons (orange). Now with the atomic weight information we can consider matching up atoms on a mass-to-mass basis. Chlorine is a chemical element with atomic number 17 which means there are 17 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
