Beryllium and iodine are different chemical elements.
beryllium
Helium (He) and Be2+ ion (not beryllium element) have the same number of valence electrons (two). But their properties are different as they differ in the number of protons (2 for helium, 4 for beryllium) and hence they differ in ther properties.
I- ion (iodine ion and not iodine) and xenon will have the same number of electrons (54 electrons)
Yes. It is the compound of the elements Beryllium and fluorine.
The same size as it is in a Helium atom
Beryllium Iodide has 1 atom of Beryllium and 2 atoms of Iodine. BeI2 is the correct formula for this compound.
Magnesium has some similarities with beryllium.
beryllium
Same group
Helium (He) and Be2+ ion (not beryllium element) have the same number of valence electrons (two). But their properties are different as they differ in the number of protons (2 for helium, 4 for beryllium) and hence they differ in ther properties.
I- ion (iodine ion and not iodine) and xenon will have the same number of electrons (54 electrons)
both a and b are true for iodine and radioactive iodine isotope
Yes they do have the same properties.
no they have to be in the same group
Compound Bal2 is also known as Barium iodide.
No, they are different
Tincture of iodine is a mixture of iodine dissolved in a potassium iodide solution. Iodine is the pure compound. At room temperate, iodine is quite unstable and tends to sublime. The tincture of iodine KI3 is used to stabilize iodine in certain experiments and as a reagent.
