Should I only be concerned about sodium ions when calculating melting temperature (Tm)?
Any charge will play a role in the Tm value for an oligonucleotide in a reaction. Thus, sodium, magnesium, and potassium concentrations each contribute to this calculation.
The IDT OligoAnalyzer™ Tool will calculate Tm for you, taking into account the presence of specific ions in the reaction buffer.
