Verified step by step guidance1
Identify the element Rn, which is radon, a noble gas located in Group 18 of the periodic table.
Determine the number of valence electrons for radon. As a noble gas, radon has a full outer shell, which means it has 8 valence electrons.
To draw the electron-dot symbol, represent the element symbol 'Rn' and surround it with dots representing the valence electrons.
Place one dot on each of the four sides of the element symbol before pairing them. This ensures that each side has at least one electron before any side has two.
Continue placing the remaining dots to complete the octet, ensuring that there are a total of 8 dots around the 'Rn' symbol, representing the full valence shell.
