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. åi·

Answer

Brief Explanations:

Aluminum (Al) has an atomic number of 13. Its electron - configuration shows that it has 3 valence electrons. In an electron - dot diagram, we represent valence electrons as dots around the symbol of the element. The given diagram has 2 dots, so one more dot is needed to correctly represent the 3 valence electrons of aluminum. Adding one dot below and one dot to the left will give a total of 4 dots which is incorrect. Adding five more dots to obey the octet rule is for a stable ion or compound formation, not for a neutral atom's electron - dot diagram. Showing all thirteen electrons is not the purpose of an electron - dot diagram which only shows valence electrons.

Answer:

He should add a single dot below the symbol.
