    Oxides of non-metals are...... in nature.

    Oxides of non-metals are usually _____ .

    While going down in the group of non-metals (14, 15, 16 and 17) the electronegative character of non-metals decreases. Typical example is of group 15 elements. The elements nitrogen (2nd period) and phosphorus (3rd period) are non-metals and their oxides are acidic in nature. The elements arsenic (4th period) and antimony (5th period) are metalloids and their oxides are amphoteric in nature. However, bismuth (6th period) is a metal. Thus, we can see that the electronegative character (non-metallic character) of elements gradually decreases and ultimately the last element becomes metal. In case of group 17 of halogens, the first member of the group i.e., fluorine is most non-metallic in character and last member of group, i.e., astatine is least non-metallic in character. In other words, the electronegative nature of the elements decreases as we move down the group. Which of the following is the most non-metallic element?
