Is this true or false two states North Carolina and Rhode Island first rejected the constitution and didn't reconsider it until after the first federal national elections were in held in 1789?

True. North Carolina and Rhode Island initially rejected the U.S. Constitution; North Carolina did so in 1788, and Rhode Island followed suit in 1788 as well. Both states did not reconsider their positions until after the first federal elections were held in 1789, when they eventually ratified the Constitution.
