PLEASE HELP ASAP I'LL GIVE BRAINLIEST: What would be the correct electron dot structure for silicon?

Which element in the third period would you expect to have the larger atomic radius, sodium (na) or sulfur (s)? a. sodium, because it has a higher effective nuclear charge attracting electrons in fewer energy levels. b. sodium, because it has fewer protons attracting electrons in the same energy levels. c. sulfur, because it has more protons attracting electrons in more energy levels. d. sulfur, because it has a higher effective nuclear charge attracting electrons in the same energy levels.

Based on the law of conservation of energy, which statement is false? answer- energy is lost when machines dont work right

Who determined the nature of chemical bonds?
