the element aluminum has an atomic number of 13. how many protons are in the nucleus of an aluminum atom? how many electrons does an aluminum atom have?

the element aluminum has an atomic number of 13. how many protons are in the nucleus of an aluminum atom? how many electrons does an aluminum atom have?

Answer

Explanation:

Step1: Recall atomic - number property

The atomic number is equal to the number of protons in an atom's nucleus. Given that the atomic number of aluminum is 13, the number of protons is 13.

Step2: Recall neutral - atom property

In a neutral atom, the number of electrons is equal to the number of protons. Since aluminum is a neutral atom and has 13 protons, it has 13 electrons.

Answer:

13 13
