c. Rb plus. Kr has 36 electrons, the same as Se2-, As3+, Sr2+, and Br-. Rb plus has 35 electrons, which is not isoelectronic with Kr.
What is the ion symbol for selenide?
A selenide contain the anion Se(2-).
What atoms or ions has the same electronic configuration as Br?
Options are not given in the question. But the following species will have the same electronic configuration as Br- ion: Neutral atom: Kr Cations: Rb+, Sr2+ Anion: Se2-
Seawater contains 0.0079 g Sr2 plus per kilogram of water. What is the concentration of Sr2 plus measured in ppm?
To convert the concentration of Sr2+ from grams per kilogram to parts per million (ppm), you can use the following formula: 1 ppm = 1 mg/L = 1 mg/kg. Given that the concentration is 0.0079 g/kg, you can convert this to 7.9 mg/kg or 7.9 ppm.
What is the ratio of Sr2 plus ions to Br- ions in a neutral compound?
In a neutral compound, the ratio of Sr2+ ions to Br- ions would be 1:2 to ensure overall charge neutrality. This means there would be one Sr2+ ion for every two Br- ions in the compound.
Is Sr2 acidic or pH-neutral?
Sr2 is pH-neutral because it does not have any effect on the pH of a solution. It is not an acid or a base, so it does not contribute to acidity or basicity.
