Which element would have the highest ionization energy? Na, Mg, Al, P

The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.

Explanation:

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
