Question

question 8 (3 points)
a neutral atom of aluminum (al) has the following subatomic particles:
______ protons
______ neutrons
______ electrons

blank 1:
blank 2:
blank 3:

Explanation:

Step1: Determine protons in Al

The atomic number of Aluminum (Al) is 13. The number of protons in an atom is equal to its atomic number. So, protons = 13.

Step2: Determine neutrons in Al

The atomic mass of Al is approximately 27. Number of neutrons = atomic mass - atomic number = 27 - 13 = 14.

Step3: Determine electrons in neutral Al

In a neutral atom, the number of electrons is equal to the number of protons. So, electrons = 13.

Answer:

Blank 1: 13
Blank 2: 14
Blank 3: 13
