Reactions of an Alkali Metal
Write a balanced equation for the reaction of cesium metal with (a) CI2(g), (b) H20(/J, (c)
Consider the following three statements about the reactivity of an alkali metal M with oxygen gas:
(i) Based on their positions in the periodic table, the expected product is the ionic oxide M20.
(ii) Some of the alkali metals produce metal peroxides or metal superoxides when they react with oxygen.
(iii) When dissolved in water, an alkali metal oxide produces a basic solution.
Which of the statements (i), (ii), and (iii) is or are true?
(a) Only one of the statements is true.
(b) Statements (i) and (ii) are true.
(c) Statements (i) and (iii) are true.
Chapter Five Compounds→ When two or more elements combine, the new substance has different properties than the elements that formed the compound. Covalent Bond→ Formed between two nonmetals. Electrons are S HARED instead of transferred. Ionic Bond→ Bond between metal and nonmetal. Solid state is a lattice of alternating...
