Verified step by step guidance1
Identify the element with atomic number 47. This corresponds to silver (Ag) on the periodic table.
Understand that silver is a transition metal. Transition metals often have variable oxidation states, but silver commonly forms a +1 charge.
Consider the electron configuration of silver: \( [Kr] 4d^{10} 5s^1 \). Silver tends to lose the single electron in the 5s orbital to achieve a stable electron configuration.
Recognize that when silver loses one electron, it forms a \( Ag^+ \) ion, which corresponds to a +1 charge.
Review the options given: +4, +3, -1, +1, +2. Based on the common oxidation state of silver, the likely charge is +1.
