(b)
Interpretation:
The element with the smallest atomic radius in group 2A is to be stated.
Concept Introduction:
In periodic table elements are arranged in increasing order of their atomic number, there are total 18 columns and 7 rows in periodic table, elements of each column show similar properties.
(c)
Interpretation:
The element with the largest atomic radius in 2nd period is to be stated.
Concept Introduction:
In periodic table elements are arranged in increasing order of their atomic number, there are total 18 columns and 7 rows in periodic table, elements of each column show similar properties.
(d)
Interpretation:
The element with the largest atomic radius in second period is to be stated.
Concept Introduction:
In periodic table elements are arranged in increasing order of their atomic number, there are total 18 columns and 7 rows in periodic table, elements of each column show similar properties.
(e)
Interpretation:
The element in group 7A with the largest ionization energy is to be determined.
Concept Introduction:
In periodic table elements are arranged in increasing order of their atomic number, there are total 18 columns and 7 rows in periodic table, elements of each column show similar properties.
Ionization energy is measure of how difficult it is to remove the most loosely held electron from an atom in the gaseous state, higher the difficulty in removing the atom; higher will be the ionization energy.
(f)
Interpretation:
The element in the group 7A with the smallest ionization energy is to be stated.
