What is the periodic trend in atomic size and electronegativity as you move from left to right on the?

1 answer:

6 0

As you move from left to right on the periodic table, atomic size and electronegativity increase.

(Ionization energy increases from left to right on the periodic table, and electronegativity relates to ionization energy in that the higher the ionization energy, the higher the electronegativity.)

(Atomic radius increases from left to right on the periodic table due to the fact that electrons are gradually being added from left to right, meaning the amount of protons in the nucleus are increasing in order to keep the atom neutral, therefore atomic size/radius increases.)

The higher the hydronium ion concentration of a solution, the ____ its pH.

pickupchik [31]

Answer:

B. Lower

Explanation:

Remember that the pH is calculated as

-log (H30 +)

That is, at a higher concentration of H30 +, with the -log, the pH value decreases and vice versa.

With a concentration 1e-5, it yields a pH of 5.00 and with 1e-2 a value of 2.00
