An element wil readily form an electrovalent compound if it electron configuration is
Answer Details
An element with 2, 8, and 1 electron configuration will readily form an electrovalent compound. This is because this electron configuration is characteristic of alkali metals, which have only one electron in their outermost shell. In order to achieve a stable electron configuration, they lose that one electron to form a positively charged ion. This ion can then combine with negatively charged ions to form an electrovalent compound. Therefore, the correct answer is "2, 8, 1."
