Election is unconditional because God has chosen His People by Grace before the foundation Eph 1:4, of course this means this means He could not have chosen them or their works. This also means it was not based upon any foreseen, works, decisions, or believing or anything they do or do not do. This is called Gods election of grace Rom 11:5-6
5 Even so then at this present time also there is a remnant according to the election of grace.
6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work.
