1. How does ionization energy change with atomic number? Use evidence from the graph to support your claim. 2. How does ionization energy change across a period and down a group on the periodic table? Use evidence from the graph to support your claim.

3. What describes an effect on ionization energy when moving down a group? Select all correct answers.

A. The ionization energy increases down a group

B. The ionization energy decreases down a group

C. The valence electrons are in energy levels farther from the nucleus

D. The shielding effect is less

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

explanation:

because it is

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
