Question

24. Element X has five valence electrons, element Y has one valence electron, and element Z has one valence electron. Which two of these elements are most likely to have similar properties? Explain your answer.

Answer 1

x and z dont have same velence electrons.... x and y have same

Answer 2

Elements Y and elements Z would have similar properties due to the fact that they both posses the same number of valence electrons. They both have a single valence electron that determines the corresponding elements bonding properties and the fact that it can either donate 1 valence electron to produce an ion that would be attracted to another atom, that is also an ion. Assuming that these elements are group 1 elements, they do not undergo in covalent bonding.
