Concept explainers
(a)
Interpretation:
An element from the given pair that has more metallic character is to be identified by using the trends within the periodic table.
Concept introduction:
The elements in a modern periodic table are arranged in an increasing order of their
The trends within the periodic table describe the change in the properties such as atomic size, ionization energy, metallic character etc. within a group or in a period.
(b)
Interpretation:
An element from the given pair that has more metallic character is to be identified by using the trends within the periodic table.
Concept introduction:
The elements in a modern periodic table are arranged in an increasing order of their atomic number. In the modern periodic table, the horizontal rows are known as periods and vertical columns are known as groups. There are seven periods and eighteen groups in a modern periodic table.
The trends within the periodic table describe the change in the properties such as atomic size, ionization energy, metallic character etc. within a group or in a period.
