Correct Part C Using the periodic table and some characteristics of an atom, you can determine the composition of subatomic particles in a neutral atom. Complete the chart, indicating the element symbol and the number of protons, neutrons, and electrons in each atom. Drag the appropriate labels to their respective targets. Hint 1. Determine the number of protons based on the element symbol The element symbol is used to identify an element. Most periodic tables display the one- or two-character element symbol prominently within each cell. The atomic number, which is the number of protons in each atom of that element, is most often displayed either above or to the upper left of the element symbol. How many protons are in an atom of iron, Fe? Express your answer as an integer. ANSWER: Hint 2. Determine the element symbol from the number of protons What element has 18 protons in the nucleus? Express your answer as an element symbol. ANSWER: Hint 3. How to determine the number of electrons In a neutral atom, the number of positively charged protons must be balanced by an equal number of negatively charged electrons. Therefore, the number of protons and electrons will be the same. Reset Help 7 8 11 13 17 18 15 19 20 24 35 1. An atom of chlorine with a mass number of 35 and an atomic number of 17 has a total of 18 neutrons. 2. An atom of nitrogen with a mass number of 15 and an atomic number of 7 has a total of 8 neutrons. 3. An atom of oxygen with a mass number of 15 and an atomic number of 8 has a total of 7 neutrons. 4. An atom of aluminum with a mass number of 24 and an atomic number of 13 has a total of 11 neutrons. 5. An atom of potassium with a mass number of 39 and an atomic number of 19 has a total of 20 neutrons. 26 protons in iron = Ar element with 18 protons =
