Question 8

An unknown element 'Z' is found to have its last electron entering a p-orbital, and it readily forms an anion with a -1 charge. Based on this information, which of the following statements is most likely true about element 'Z'?

Accepted Answer

C. It is a halogen, typically found in Group 17 of the periodic table. — An element with its last electron entering a p-orbital belongs to the p-block. Forming an anion with a -1 charge signifies that the element needs one electron to achieve a stable octet configuration. This characteristic property belongs to Group 17 elements, also known as halogens. Noble gases are chemically inert and do not readily form ions, s-block elements typically form cations, and d-block elements (transition metals) usually form cations with variable valencies.

Accepted Answer

C. Lowland for flooding, Highland for landslides. — The Lowland region, being flat, low-lying, and crisscrossed by numerous rivers and backwaters, is highly vulnerable to severe flooding, especially during heavy monsoons.
