(a)
Interpretation:
The name, atomic symbol and group number of the element with Z value 33 is to be determined. Also, classify the element as metal, metalloid, and nonmetal.

(b)
Interpretation:
The name, atomic symbol and group number of the element with Z value 20 is to be determined. Also, classify the element as metal, metalloid, and nonmetal.
Concept introduction:
A periodic table is an arrangement of elements based on their atomic number, properties and electronic configuration. The table is arranged into groups and periods. The elements which are metallic in nature, occupy the large lower-left portion of the table. The non-metals occupy the small upper-right portion of the table. Metalloids like along the staircase line. Elements which appear in the same group have similar behaviour.
(c)
Interpretation:
The name, atomic symbol and group number of the element with Z value 35 is to be determined. Also, classify the element as metal, metalloid, and nonmetal.

- Calculate the pH and the pOH of each of the following solutions at 25 °C for which the substances ionize completely: (a) 0.000259 M HClO4arrow_forwardWhat is the pH of a 1.0 L buffer made with 0.300 mol of HF (Ka = 6.8 × 10⁻⁴) and 0.200 mol of NaF to which 0.160 mol of NaOH were added?arrow_forwardDetermine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR. Be sure to include the proper phases for all species within the reaction. NaN₃arrow_forward
