Answer:

Boiling water is endothermic while condensing is exothermic.

Explanation:

Our experience makes it easy for us to realize that to boil water or any liquid and thereby convert into a gas, heat is required and the process is endothermic. It is less intuitive to grasp that when a gas condenses to a liquid, heat is given off and the process is exothermic.

The element iodine forms a(n) _______ with the charge . The symbol for this ion is , and the name is . The number of electrons i
-BARSIC- [3]

Answer:

The element iodine forms an anion with the charge -1. The symbol for this ion is I⁻¹, and the name is iodide. The number of electrons in this ion is 7.

Explanation:

Hello,

In this case, we have to consider iodine has the capacity to accept the electrons lost by other elements such as metals or hydrogen by becoming negatively charged. Such phenomena makes iodine to form an anion (negatively charged) with the charge -1, since it only needs one electron to attain the octet. Moreover, the symbol of such ion is I⁻¹ and its name is iodide. By cause of the aforementioned, the number of electrons it has is 7 since at its outer shell seven electrons are found (see electron configuration Kr,5s²,5p⁵).

Best regards.
