Write the equation for the interaction of phosphorus with calcium when heated. Which atom, phosphorus or calcium

Write the equation for the interaction of phosphorus with calcium when heated. Which atom, phosphorus or calcium, is more electronegative? What properties, oxidizing or reducing, does phosphorus exhibit in this reaction?

3Ca + 2P-> Ca3P2 (calcium phosphide)
Phosphorus is a more electronegative element than calcium. Therefore, in reaction with calcium, phosphorus exhibits oxidizing properties.
