Interpretation:
The change in chemical properties of oxides change from left to right across a period and from top to bottom within a particular group 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
Oxide is the compound formed when oxygen reacts with another element. Oxides formed with metals are basic
Oxides formed with metals are basic. Most of oxides formed with nonmetals are acidic.
Amphoteric oxides have the properties of bases and acid. Elements that are in the intermediate position of periodic table form amphoteric oxide.

- Which halogen has the highest ionization energy? Is this what you would predict based on what you have learned about periodic properties?arrow_forwardConsider the elements in Column 15 in the periodic table, with nitrogen at the top (2nd period) and bismuth in the 6th period. a) How would you expect the oxides of these elements to react with water? b) Applying the analogous concepts of metallic versus non-metallic character, would the oxides of N produce an acidic or basic solution in water? What about an oxide of Bi?arrow_forwardAlkali metals form several binary oxides (molecules containing only the metal and oxygen). What are the products formed by reacting lithium, sodium, and cesium with excess oxygen? Explain why they are different (consider the trend in cation size down the group), and name each oxide.arrow_forward
