It''s Elemental - The Element Chromium

Chromium is a blue-white metal that is hard, brittle and very corrosion resistant. Chromium can be polished to form a very shiny surface and is often plated to other metals to form a protective and attractive covering. Chromium is added to steel to harden it and to form stainless steel, a steel alloy that contains at least 10% chromium.

Calcium nitrate | Ca(NO3)2 - PubChem

Calcium nitrate soln (0.5, 0.25 M), alone or in coination with sucrose, were toxic to stem and flower (carnation) tissue prior to freezing. Calcium nitrate alone offered no protection at -4 °C. Flowers pretreated with 0.125 M calcium nitrate appeared translucent or water-soaked after 5 days at -4 °C.

Why is the melting point of magnesium less than that …

Excellent question. I’ll try to answer it. You see Calcium and Magnesium are group two elements. The Group 2 elements are all metals with metallic bonding, so you expect their melting points to be high. In metallic bonding, metal ions in a meta
