2024年6月14日 · Strontium, a group 2 element, will lose 2 electrons to attain a noble gas configuration because it will achieve a stable electron configuration similar to the nearest noble gas, which is krypton.

2023年8月10日 · Strontium, a group 2 element, will lose 2 electrons to attain a noble gas configuration because it will achieve a stable electron configuration similar to the nearest noble gas, which is krypton.

2023年8月31日 · Strontium, a group 2 element, will lose 2 electrons to attain a noble gas configuration because it will achieve a stable electron configuration similar to the nearest noble gas, which is krypton.

2016年6月16日 · The complete electron for a neutral arsenic atom is: "1s"^2"2s"^2"2p"^6"3s"^2"3p"^6"3d"^(10)"4s"^2"4p"^3 Its shorthand electron configuration is: ["Ar"]"3d"^(10)"4s"^2"4p"^3 As is the chemical symbol for the element arsenic. Its atomic number is 33, which is the number of protons in the nuclei of its atoms. In a neutral atom, the number …

2015年11月21日 · Here's what I got. Your starting point for this problem will be the electron configuration for a neutral strontium atom in its ground state, which looks like this "Sr: " 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^6 color(red)(5)s^2 As you can see, strontium's outermost electrons are located on the fifth energy level, in the 5s-orbital. In order to completely describe …

2024年11月15日 · The noble gas element strontium (Sr) has the electron configuration of [Kr]5s^2. This means that it has the same electron configuration as krypton (Kr), with two electrons in its outermost shell (5s).
