Question

question 7 (3 points)
a neutral atom of sodium (na) has the following subatomic particles:
______ protons
______ neutrons
______ electrons
blank 1:
blank 2:
blank 3:

Explanation:

Step1: Determine protons in Na

The atomic number of Sodium (Na) is 11. The number of protons in an atom is equal to its atomic number. So, protons = 11.

Step2: Determine neutrons in Na

The atomic mass of Sodium is approximately 23. The number of neutrons is calculated as atomic mass - atomic number. So, neutrons = 23 - 11 = 12.

Step3: Determine electrons in neutral Na

In a neutral atom, the number of electrons is equal to the number of protons. So, electrons = 11.

Answer:

Blank 1: 11
Blank 2: 12
Blank 3: 11
