How many ions does rubidium have?
Rb atom has 37 electrons and 37 protons. when 1 electron is removed number of protons remains 37 but number of electrons is 36.36 negative charges is balanced by 36 positive charges. one extra proton is present so 1 positive charge.
Is aluminum selenide ionic?
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Aluminium selenide, also known as aluminum selenide or aluminium(III) selenide, is a chemical compound. … It contains aluminium and selenide ions.
Is aluminum selenide ionic or covalent?
It is probably best described as a polar covalent network compound. The difference in electronegativity Al-Se (0.94) is pretty modest and quite similar to that in C-O, but the compound is a solid with a network structure.

What is the positive ion in potassium selenide?
Two potassium ions, each with a charge of 1+, would give us two positive charges, while one selenide ion, with a charge of 2−, would give us two negative charges. Therefore, the formula is two potassium ions to one selenide ion: K2Se.
What is the correct formula for barium oxide?
Barium oxide has the formula BaO . It’s an ionic compound, so its formula represents the lowest whole number ratio of elements in the compound. So Ba2O2 should be reduced to BaO . The formula for the lead (II) ion is Pb2+ .
