I hate that I always have to waste my limited quanitty of questions for follow ups for a decent explaination.I don't understand.It must be in a +3 state?Why?F has a -1 charge, that means it would have:9p 10e due to it's 18.99 mass.and since the charge is -1, that would imply 10e.That means I need an element with +1 charge to balance, but also should have 12e.Mn has a charge of +2 generally, but it can have +3.I was given zero understanding of how it could be any element with a +1 charge that has those numbers of electrons.I need help understanding this.
Nitrogen has a greater first ionization energy than phosphorus. What is the best evidence to supportthis observation?
A. A main group element with the Valentine electron consigration 4S24P5 is imperiotic croop____. It forms a monatomic ion with a charge of ____. B. A manger element with the valence electron configuration 3S1 is in periodic group____. It forms a monotomic ion with a charge of____.
I need help with this question that is attached. Table 1.4 gave the ionic radii in pm. For k+ it was 138(6), 151(8),159(10) and for f- it was 128(2), 132(4), 133(6). Table 1. 5 gave ionization energies in kj/mol. For k they were 419, 3051 and 4410. For f it was 1681,3375, and 6050. Table 1.6 gave electron affinities in kj/mol and for k it was 48 and for f it was 328. I've also attached the resource table
