What else can I help you with?
What is the noble gas that has the same Lewis structure as Se2?
Krypton (Kr) has the same Lewis structure as Se2. Both molecules have 16 valence electrons arranged in a linear structure with a single covalent bond.
What noble gas is isoelectronic with the selenium?
None. The Se2- ion is isoelectronic with Krypton.
What would have to gain two electrons in order to achieve the same number of electrons as a noble gas O or Sr or Na or Se or Br?
Oxygen, O ,and selenium Se. O (oxygen) would have to gain two electrons in order to achieve the same number of electrons as Ne (neon, a noble gas). Selenium would gain two to achieve the same number of electrons as Kr, krypton (noble gas). They would form the oxide, O2- and selenide Se2- ions
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-
What is the name for a selenium ion with 36 electrons?
When selenium gains two electrons, it becomes the selenide ion.
What is the noble gas that has the same Lewis structure as Se2?
Krypton (Kr) has the same Lewis structure as Se2. Both molecules have 16 valence electrons arranged in a linear structure with a single covalent bond.
What noble gas is isoelectronic with the selenium?
None. The Se2- ion is isoelectronic with Krypton.
What is the ion symbol for selenide?
A selenide contain the anion Se(2-).

Oxygen, O ,and selenium Se. O (oxygen) would have to gain two electrons in order to achieve the same number of electrons as Ne (neon, a noble gas). Selenium would gain two to achieve the same number of electrons as Kr, krypton (noble gas). They would form the oxide, O2- and selenide Se2- ions
Place the following atoms or ions in order of increasing radius O O2- S2- and Se2-?
O, O2-, S2-, and Se2-O is smaller than O2- because O2- has 2 extra electrons but the same amount of protons as O, so they are held less tightly and the atom is bigger. Atom size increases as you move down the periodic table, so O2- < S2- < Se2-.
What is the formula for selenide?
Se2-
Which ion has the largest radius Se2- As3-?
The Se2- ion has the largest radius because it has more electrons than As3-, leading to increased electron-electron repulsion and a larger atomic radius.
What is the chemical formula for selenide?
Formula: Se2-
HOW DO YOU name Se2?
SELENIDE
How many ion atom are formed in selenium?
The oxidation states of selenium are: -2, +2, +4, +6.
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.
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-
