Look for the atomic mass of the element. This is because chlorine contains two different isotopes, chlorine-35 and chlorine-37. Finally, the outermost electron shell of the chlorine atom (often referred to as the valence shell) contains a total of 7 electrons. 10 3 An uncharged atom of boron has an atomic number of 5 and an atomic mass of 11. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. Step 1: For the number of protons, it is equal to the atomic number. 19F1-A. Q: 10. Therefore, Beryllium will have four protons, four neutrons, and two electrons. Show transcribed image text. So there are (9-4) neutrons.... or 5 neutrons. previous Chlorine can be found in the periodic table with an atomic number of 17. For example, the relative atomic mass of chlorine is 35.5 rather than a whole number. A. Protons and Neutrons in Chlorine. 1 decade ago. An element’s atomic mass (also known as the atomic weight) is the weighted average mass of atoms of an element. there are 17 protons, 17 electrons and 37-17 or 20 neutrons. that means it is not ionic in form. 2 neutrons B. The atomic number is the number of protons an atom has in its nucleus. 0.287 M 20. How many electrons are there in the neutral atoms? 0.189 M 30. For chlorine, Cl, the atomic number is 17. How many protons and how many neutrons are there in each isotope? The mass number is the sum of protons and neutrons, so for Cl-35, there are 35-17 = 18 neutrons. The isotope of chlorine is 17Cl37, and the 37 represents the "mass number", NOT the "atomic mass". the proton number shows the number of protons in the atom. Thus, for Chlorine-37 . *Response times vary by subject and question complexity. Careful. ionic 6 13 neutrons C. 4 neutrons D. 7 neutrons The atomic number of fluorine is 9. 0 0.
