Amagnesium (mg) atom gives one electron to two atoms of another element, then it takes on a 2+ charge. the two atoms of the other element each form a 1− charge. as a result, the magnesium ion and the two ions of the other element attract and form an ionic bond.

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
