convert your atom into an ion. remember to follow the octet rule. calculate the ionic charge: # protons (+) - # electrons (-) ionic charge write the symbol and charge for the ion.

Answer

Explanation:

Step1: Determine number of electrons in neutral atom

The atomic number is 13 (number of protons), so a neutral atom has 13 electrons.

Step2: Apply octet - rule to form ion

The outermost shell has 3 electrons. To follow the octet - rule, it will lose 3 electrons.

Step3: Calculate ionic charge

Number of protons = 13. After losing 3 electrons, number of electrons = 13 - 3=10. Ionic charge = # protons - # electrons = 13 - 10 = + 3.

Step4: Write ion symbol

The element with atomic number 13 is aluminum (Al). The ion symbol is $Al^{3 + }$.

Answer:

Ionic charge: + 3 Ion symbol: $Al^{3 + }$
