(a)
Interpretation:
The name, atomic symbol and group number and period of the element with Z value 14 is to be determined. Also whether the element is a metal, non-metal or a metalloid is to be determined.
Concept introduction:
A periodic table is an arrangement of elements based on their
(b)
Interpretation:
The name, atomic symbol and group number and period of the element with Z value 55 is to be determined. Also whether the element is a metal, non-metal or a metalloid is to be determined.
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.
