HOW DO YOU name Se2?
SELENIDE
What is the ion symbol for selenide?
A selenide contain the anion Se(2-).
What is the formula for selenide?
Se2-
What is the name for a selenium ion with 36 electrons?
When selenium gains two electrons, it becomes the selenide ion.
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-
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-.
How many ion atom are formed in selenium?
The oxidation states of selenium are: -2, +2, +4, +6.
What is the name of this chemical formula - SeH2?
Hydrogen Selenide and it is extremely toxic when inhaled.
Se2 Br1 Rb1 plus and Sr2 plus are all with Kr?
isoelectronic
What noble gas is isoelectronic with the selenium?
None. The Se2- ion is isoelectronic with Krypton.
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.
