describing an element\nthe element aluminum has an atomic number of 13.\nhow many protons are in the nucleus of an aluminum atom?\nhow many electrons does an aluminum atom have?
Answer
Answer:
- 13
- 13
Explanation:
Step1: Recall atomic - number property
The atomic number is equal to the number of protons in an atom's nucleus. Since the atomic number of aluminum is 13, the number of protons in the nucleus of an aluminum atom is 13.
Step2: Consider neutral - atom charge balance
In a neutral atom, the number of electrons is equal to the number of protons. Aluminum is neutral in its standard state, so it has 13 electrons.
