Answer:

a lithium

Explanation:

The elements in the second period are lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon. In the second period, the atomic radius of the elements decreases across the period, thus lithium has the highest atomic radius of 152 picometer while neon has the least [67 picometer

Which one of the following statements best describes a solution with a pH of 3?
zalisa [80]

Statement D is the correct option as the solution will have pH of 3. It has an H3O+ ion concentration of 1 × 10^{-3} mol/L and is acidic.

Explanation:

It is given in question that solution must have pH of 3. The value if being less than 7 shows that solution is acidic. The pH value of 3 indicates that given solution is highly acidic and has strong acid. Strong acid gets fully dissociated into H_{3}O^{+} ions.

pH of the solution is calculated as:

pH = -log10[H_{3}O^{+}]

the concentration or molarity of the hydronium ion is given as moles/litre

concentration of hydronium ion in the solution is 1 X 10^{-3} moles/litre

putting the values in the equation:

pH = - log10( 1 X 10^{-3})

pH = 3 (acidic)

Thus it can be concluded that D option is the right answer.
