Which one of the following is not isoelectronic with Kr a. As3 plus b. Se2- c. Rb plus d. Sr2 plus e. Br-?
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.
How many total electrons are in a Sr2 ion?
Sulfur's atomic number is 16. Neutral sulfur would then have 16 protons and 16 electrons. Since we're dealing with S2- though, we need to add 2 electrons to this, making 18.
Write the chemical symbol for the ion with 95 protons and 89 electrons?
the number of protons stay the same in every element (i think). So the number of protons is the atomic number. Therefore, this is tungsten (W). The electrons and nuetrons are the only thing that change.
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.
What noble gas has the same electron arrangement as Sr2?
Krypton has the same electron arrangement as Sr2. Both have a total of 36 electrons arranged in outer shells with the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6.
Which one of the following is not isoelectronic with Kr a. As3 plus b. Se2- c. Rb plus d. Sr2 plus e. Br-?
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.
How many electrons in Sr2 plus?
Strontium (Sr) has an atomic number of 38, meaning it has 38 electrons in its neutral state. When it loses two electrons to become Sr²⁺, it has 36 electrons remaining. Therefore, Sr²⁺ has 36 electrons.
The Strontium ion would have how many electrons?
The strontium ion is Sr2+ with the same electron configuration as Kr. Sr element has an atomic number of 38- the neutrl Sr tom has 38 protons in its nucleus and 38 electrons - therefore the ion Sr2+ has 2 less - 36.
How many total electrons are in a Sr2 ion?
Sulfur's atomic number is 16. Neutral sulfur would then have 16 protons and 16 electrons. Since we're dealing with S2- though, we need to add 2 electrons to this, making 18.
How many electrons will strontium gain or lose in forming an ion?
It will lose 2 to form Sr2+
Se2 Br1 Rb1 plus and Sr2 plus are all with Kr?
isoelectronic

What is the symbol for an ion having 35 protons and 36 electrons and 45 neutrons?
This is the anion of the isotope arsenic-73: 73As3-; it is impossible to write correct in WikiAnswers.
What noble gas has the same number of electrons as strontium?
No, Strontium is an alkaline earth metal which exists in solid state.
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.
Will strontium gain electrons in chemical change?
Strontium typically loses electrons to form a positively charged ion (Sr2+). It is in group 2 of the periodic table, meaning it tends to lose two electrons to achieve a stable electron configuration.
