WebBecause this element is located in Group 17, or 7A, on the periodic table, it will ionize to form an anion with a –1 charge. Therefore, the resultant ion is symbolized as I– 1 and is named the iodide ion . Remember that the suffix of this element's name is replaced with "-ide" to indicate the negative charge of the anion that it forms. WebNotice that every addition of hydronium ion reduces the negative charge of the parent anion by one. An older method of naming these ions is using the prefix bi-. Thus HCO3- is … Webwhich of the following options correctly describe the group 8A elements? -they're called the halogen group. -they exist as diatomic species. -they have very low electron affinities. -they have low ionization energies. -all group 8A elements with n ≥ 2 have filled outer ns and np subshells. -they have very low electron affinities. hbo r ratings movies
