sal drew the electron dot diagram of an aluminum atom as shown. how should sal correct his diagram? he should add five more dots so that the atom obeys the octet rule. he should add ten more dots so that all thirteen electrons are shown. he should add a single dot below the symbol. he should add one dot below and one dot to the left of the symbol.
Answer
Brief Explanations:
Aluminum (Al) has an atomic number of 13. Its electron - configuration is 2, 8, 3. In an electron - dot diagram, we only show the valence electrons. Aluminum has 3 valence electrons. The given diagram shows 2 valence electrons. So, one more dot needs to be added to represent all the valence electrons. Adding one dot below and one dot to the left will make it show 4 valence electrons which is incorrect. Adding five more dots to obey the octet rule is wrong as we are just representing valence electrons of a single atom here, not forming a compound to follow the octet rule. Showing all thirteen electrons is not the purpose of an electron - dot diagram for a single atom. Adding a single dot below the symbol will make it show 3 valence electrons.
Answer:
He should add a single dot below the symbol.
