Q. How many protons are in Ag?
Answer
To find the number of protons in atomic silver (Ag), use the atomic number of Ag.
Silver (Ag) has atomic number \(47\), so it has \(47\) protons.
\[
\text{Number of protons} = 47
\]
Detailed Explanation
We want the number of protons in an Ag (silver) atom.
Step 1: Identify what “protons” means.
Each proton has a positive charge, and the number of protons in an atom is equal to the atom’s atomic number.
Step 2: Look up the atomic number of silver (Ag).
Silver, Ag, has atomic number \(47\).
Step 3: Conclude the number of protons.
Because the atomic number equals the number of protons in the nucleus, the number of protons in Ag is
\[
\text{Number of protons in Ag} = 47
\]
Final Answer: \(\boxed{47}\) protons.

General Chemistry FAQs
What determines the number of protons in an atom?
The number of protons equals the atomic number \(Z\). For a neutral atom like Ag, protons \(=\) \(Z\).
What is the atomic number of silver (Ag)?
Silver (Ag) has atomic number \(Z = 47\). So it has 47 protons.
How many protons are in a silver ion, like \( \text{Ag}^+ \)?
Ions change electrons, not protons. So \( \text{Ag}^+ \) still has 47 protons.
If the mass number of Ag is given, does that change the proton count?
No. The mass number \(A\) affects neutrons: \(n = A - Z\). Protons remain \(Z = 47\) regardless of \(A\).
How do I find protons from the periodic table entry?
Look up Ag’s atomic number on the periodic table. The atomic number is the proton count: \(47\) protons.
What is the relationship between protons, neutrons, and mass number for silver?
Use \(A = Z + n\). For Ag, \(Z = 47\), so neutrons \(n = A - 47\). Protons stay 47.
How many protons are in \(^{107}\text{Ag}\)?
The specific isotope changes neutrons only. For \(^{107}\text{Ag}\), protons \(= Z = 47\).
