Answer:
The outer shells of non metal atoms gain electrons when they form ions this result in the formation of negative ions
The Bronsted base in H2S +H2O → H3O^+ + HS^- is H2O
Explanation
According to Bronsted Lowry definition of an base , that is a base is a compound that act as a protons acceptor. These protons are in form of hydrogen ions . H2O in the above equation accept one hydrogen ions to form H3O^+
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.
