Chapter 5: Problem 18

For each of the questions, four choices have been provided. Select the correct alternative. An element \(\mathrm{X}\) has low ionization energy and another element \(\mathrm{Y}\) has high electron affinity. The bond formed between them could be (a) ionic (b) polar covalent (c) coordinate covalent (d) non-polar covalent

Short Answer

Expert verified
Answer: (a) Ionic

Step by step solution

01

Understanding terms involved

Ionization energy is the energy required to remove an electron from an atom. A low ionization energy means that it is relatively easy to remove an electron from element X. Electron affinity is the energy released when an atom gains an electron. High electron affinity means that element Y readily accepts electrons.
02

Predicting bond formation

When an element with low ionization energy combines with an element having high electron affinity, one can transfer an electron from the first element to the second, forming ions. The resulting positively charged ion (cation) and negatively charged ion (anion) will attract each other, leading to the formation of an ionic bond.
03

Answer

Given the properties of the two elements, the most likely bond type formed between them is ionic. Thus, the correct answer is (a) ionic.
