(a)
Interpretation:
The trend of metallic character, atomic size, ionization energy and acidity of oxides is whether increases or decreases from left to right across a period has to be determined.
Concept Introduction:
According to physical and chemical properties, the elements can be further divided into metals, non-metals and metalloids.
In a group, the metallic character of an element increases from top to bottom whereas in a period, it decreases from left to right.
The classification elements in the periodic table as metals, nonmetals, or metalloids can be given as
Atomic radius is the distance between the atomic nucleus and outermost shell having electrons of an atom. From the atomic radius, the size of atoms can be visualized
The ionization energy is the minimum energy required to remove the electron from an isolated atom which is in the gaseous state results to give gaseous ion with one positive charge.
Oxide is a compound that is formed when oxygen reacts with another element. Oxides formed with metals are most probably basic. Most of oxides formed with nonmetals are acidic.
