Explanation:

Step1: Recall atomic structure relationships

In a neutral atom, the number of electrons equals the number of protons. The atomic mass is approximately the sum of protons and neutrons.

Step2: Calculate for Fluorine

Number of neutrons: \(19 - 9=10\). Number of electrons (since neutral) \( = 9\).

Step3: Calculate for Calcium

Number of protons \( = 20\) (atomic number). Number of electrons \( = 20\).

Step4: Calculate for Hydrogen

Atomic mass \( = 1\). Number of electrons \( = 1\).

Step5: Calculate for Silicon

Number of electrons \( = 14\).

Step6: Calculate for Boron

Atomic mass \( = 11\). Number of neutrons \(=11 - 5 = 6\).

Step7: Calculate for Helium

Atomic number \( = 2\). Number of protons \( = 2\).

Step8: Calculate for Lithium

Number of neutrons \(=7 - 3 = 4\). Number of electrons \( = 3\).

Step9: Calculate for Chlorine

Atomic number \( = 17\). Atomic mass can be calculated if more info (but assume standard). Number of neutrons \(=\) (if atomic mass is say \(35.5\) but here maybe \(18\) if atomic mass \(35\) but let's assume from table context). Number of electrons \( = 17\).

Step10: Calculate for Nitrogen

Number of protons \( = 7\). Number of neutrons \(=\) (if atomic mass \(14\) then \(7\)).

Step11: Calculate for Beryllium

Atomic number \( = 4\). Number of neutrons \(=9 - 4 = 5\).

Step12: Calculate for Sodium

Atomic number \( = 11\). Number of protons \( = 11\). Number of neutrons \(=23 - 11 = 12\). Number of electrons \( = 11\).

Step13: Calculate for Carbon

Number of neutrons \(=12 - 6 = 6\).

Step14: Calculate for Potassium

Atomic number \( = 19\). Number of protons \( = 19\). Number of neutrons \(=39 - 19 = 20\).

Step15: Calculate for Oxygen

Atomic number \( = 8\). Number of protons \( = 8\). Number of electrons \( = 8\).
