Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Depending on your definition of life, only Carbon, Hydrogen, Nitrogen and Oxygen. The least you can call living is an autocatalytic RNA molecule.

"Magnesium is essential to cell function and is found in every cell type of every organism" tells you nothing about primitive life.

However, it is most likely that life arose in the sea. Sea water is rich in Chloride, Sodium, Magnesium, Sulphate, Calcium, Potassium, Carbon, Bromide, Boron, Strontium and Fluoride [there is an issue of how much this composition depends on the fact that life has been present for billions of years] and you would espect those elements to play a role in Earth life.

Those whom the Gods wish to destroy They first make mad. -- Euripides
