Therefore, the second level . 7 3. b. Number of Energy Levels: 3 First Energy Level: 2 Second Energy Level: 8 Third Energy Level: 7 Isotopes. A maximum of two electrons can be found in the \(n=1\) level; eight electrons can be in the \(n=2\) level. Chlorine-37 is composed of 17 protons, 20 neutrons, and 17 electrons. Atoms are most stable when their outermost energy level is full of electrons. Periods. Chlorine-36 is composed of 17 protons, 19 neutrons, and 17 electrons. answer choices . The electronic configuration of chlorine can be written as 2, 8, 7. 6. 2, 8, 7 electrons are distributed in the shells K, L, M respectively. a. How many electrons does chlorine have in its highest energy level? Which is true for Chlorine? The distance from the nucleus increases with each subsequent energy level/Electrons Draw & label examples of molecules with a double & triple bond using a structure diagram. 8 b. Groups. Horizontal rows of elements that share the same number of ENERGY LEVELS but DO NOT share chemical properties. atom. In writing the electron configuration for Chlorine the first two electrons will go in the 1s orbital. 5. All other isotopes have half-lives under 1 hour, many less than one second. How many valence electrons does the sodium atom appear to have now? How many valence electrons does chlorine have? How many valence electrons does carbon have? What does each line mean? Each line means a single bond between a pair of electrons. SURVEY . Chlorine (Cl) is in Group 17. Designed to promote understanding of chlorine chemistry. chlorine has an electron arrangement of 2.8.7. it is not stable so it accepts one electron to stabilise and become an ion with arrangement of 2.8.8. The . Seven Draw a structure (line) diagram illustrating the molecule CH 4. Does nitrogen have in its first energy level? As the energy level increases, the energy difference between them decreases. 2 c. Does chlorine have in its highest energy level? As shown in the figure below, there are multiple energy levels where electrons can be found. The p orbital can hold up to six electrons. Hence, the valency of chlorine is 1. 5. 4. is now the outermost, with eight electrons. answer choices . Electrons orbit the atom's nucleus in energy levels. Since 1s can only hold two electrons the next 2 electrons for Chlorine go in the 2s orbital. Describe the relationship between the number of energy levels and the distance from the nucleus. Outer energy level. Where are valence electrons located within an atom? Does potassium have in its third energy level? Chlorine-35 is composed of 17 protons, 18 neutrons, and 17 electrons. Therefore, valence electron in chlorine is 7 and it needs to gain 1 electron from the outermost orbit to attain octet. 38. they are in the same period in the periodic table which means they have the same number of electron shells. therefore, the answer is H. It is in the Halogen Family. Neutral chlorine atoms have electrons in the first three energy levels in its ground state. Answer3 energy levels17 protons and electrons. metals. Tags: Question 56 . answer choices . How many electrons can the second energy level closest to the nucleus hold? It is in Group 17. Determine the number of electrons a chlorine atom needs to gain in order to have a full outer energy level (complete octet like a noble gas). c. How many valence electrons does the chlorine atom have now? third energy level of the sodium atom is now empty. The next six electrons will go in the 2p orbital. This table shows the pattern in the periodic table that Mendeleev developed and how the missing elements at that time could be predicted. a.
