hard because it has calcium and magnesium
Answer:
c.Elements in the compound shares electrons
Explanation:
Because in ionic compounds element lose or gain electrons only
Sharing of electrons is the property of covlant compounds.
It is predicted to lie at a wavelength of 91.2 nm.
Rydberg equation is a mathematical formula that is used to predicts the wavelength of light resulting from an electron moving between energy levels of an atom. Rydbery equation is used to describe the spectral wavelengths of chemical elements. The equation is made up of different components, which include n1 and n2. The n1 of the equation has a value of 1 while the n2 runs from 2 to infinity; this makes the spectral lines to converge at point 91.2 nm.
