Cl is 17 and it's electronic configuration is 2,8,7. Chemistry, 21.06.2019 23:00. Period = number of valence electrons = 3. It is known to be one of the following elements: carbon, germanium, sulfur, cesium, beryllium, or argon. The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. In which period of the periodic table is it found? This answer has been confirmed as correct and helpful. 20. Subtract the number of electrons from the protons. 18 electrons The wording in the question is clumsy. However, if we allow for charged atoms, in other words ions, then the answer is not definite. The element lithium (Li) has 3 protons and 3 electrons. Therefore chlorine is the element that has 17 protons. The electron configuration states where electrons are likely to be in an atom. If an ion contains 50 protons,68 neutrons and 48 electrons.what is its symbol? 3. (b) What happens to the number of valence electrons in the atoms of elements as we go down in a group of the periodic table? Answer the questions below for an element that has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s1. Of these 90, only 25 or so are used to build living things. Access a diverse Question Bank and ask You Own Doubt Now! A. Consider an atom which has 9 protons, 10 neutrons, and 9 electrons. Earn a little too. The Atomic number of chlorine I.e. ...” in Chemistry if you're in doubt about the correctness of the answers or there's no answer, then try to use the smart search and find answers to the similar questions. For example, chlorine has two isotopes with atomic number 17 but mass numbers as 35 and 37. Chemestry. In this case, the atom adds or gains an electron making the number of electrons to go from 17 to 18. What element has 30 neutrons and 15 electrons in the 3rd level? The number of protons is the atomic number, which being 47 identifies this element as Silver (Ag). The table shows the 11 most prevalent elements in the lithosphere (the earth's crust) and in the human body. Comment; Complaint; Link; Know the Answer? If elements are represented with charges they are called as ions. 17 protons means it is Chlorine. Median response time is 34 minutes and may be longer for new subjects. WINDOWPANE is the live-streaming social network that turns your phone into a live broadcast camera for streaming to friends, family, followers, or everyone. The element with 16 neutrons, 15 protons, and 15 electrons is phosphorus. B. An atom of an element has a total of 13 electrons. Finding Valence Electron with a Periodic Table: Transition Metals. check_circle Expert Solution. Elements consist of only one kind of atom and cannot be decomposed into simpler substances. Hence the element is Chlorine. You know that nitrogen-14 has 7 protons in the nucleus because it is an isotope of nitrogen, which has an atomic number equal to 7. How many electrons are in Cl ion? And thus we got the element #"chlorine"#, for which #Z=17#. Element X consists of 17 protons and electrons and 18 neutrons. The element chlorine has 17 protons and 17 electrons. (e) If the nucleus of an atom has atomic number 17 , mass number 37 and there are 17 electrons outside the nucleus, the number of neutrons in it Atom Ions and Isotopes. Protons and Neutrons in Chlorine. And thus we got the element #"chlorine"#, for which #Z=17#.The wording in the question is clumsy. Not Sure About the Answer? Weegy: One gram of carbohydrate contains 4 CALORIES. What is the electron configuration for a sodium ion? The additional electron means that the chloride ion has a charge of 1-. with 18 neutrons the atomic mass is 17+18=35. [ An atom of chlorine if it gains electrons, It becomes negatively charged. ] Alternatively, there are 3 shells of electrons so the element is in period 3, and the last shell has 7 electrons so it is in Group (17 or VIIA). The mass of chlorine is the sum of all the elementary particles present in the atom which includes protons, neutrons and electrons. So, Atomic number of X (Z) = 17. I know that chlorine has 17 protons and 18 neutrons, but the number of electrons is supposed to be equal to the number of protons. One gram of carbohydrate contains ____ calories. Chlorine is a chemical element with atomic number 17 which means there are 17 protons in its nucleus. A neutral atom is an atom where the charges of the electrons and the protons balance. See all questions in Electron Configuration. 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. In the ion formed by X: (i) Number of protons = 17 (ii) Number of electrons = 18 (iii) Number of neutrons = 18 The answer is 10. What is the electron configuration of chromium? How many electrons does it have? The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. What happens to an atom of chlorine if it gains electrons, The element chlorine has 17 protons and 17 electrons. The atomic number is the number of electrons present in an atom. First and foremost, supervisor - - - . A. What is the electron configuration for a nitride ion? Iknow #2 is d. i just need to know why. Cl minus ion (Ignore the stuff about isotopes, that's different numbers of neutrons) Atom of an element has 17 protons, 17 electrons and 18 neutrons, a) Calculate the mass number of the element 1 See answer mt6000500 is waiting for your help. Neissa_Saint-Louis. The mass of electrons… Chem help. 17 Give the complete electron configuration for this element, 18 19 How many valence electrons does it have? Answer the questions below for an element that has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s1. a. depletion of oxygen in the water. Electron affinities are negative numbers because energy is released. The number of protons defines a chemical element, in this case 17=Chlorine. Therefore, the number of electrons in neutral atom of Chlorine is 17. When the number of electrons and protons are the same, such an atom is neutral. Before answering your question you intended to ask ,basic chemistry says that elements can't have charges . An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35 particles in the nucleus) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 particles in the nucleus). Solution: Atomic number = Number of protons or number of electrons = 4. atomic number 3. 17 protons means it is Chlorine. What happens to an atom of chlorine if it gains electrons. 22. Find an element from Groups 3 to 12. What is the symbol for this element? Share what’s outside your window and all around you. An element with 13 electrons has 13 protons in a neutral atom (net charge=0). Weegy: Oracle bones from the Shang dynasty contain the first examples of Chinese writing. (Tiny amounts — sometimes only a few atoms — of additional elements have been made in nuclear physics laboratories, but they play no role in our story). Finding Valence Electron with a Periodic Table: Transition Metals. 4. What are its atomic number and mass number ? T. The charge and identity of an ion with 16 protons, 18 electrons and 17 neutrons would be?
