To yield a compound that is fully active, a molecule of vitamin D must be chemically altered by kidney and liver tissues. In the liver, it's converted to calcidiol, and in the kidneys, to calcitriol.
Liver and kidney
Retinal
precursors
No uranium is not chemically active
No. Acetic acid (the 'active' ingredient in vinegar) is structurally, physically and chemically very different to vitamin C (an isomer of ascorbic acid).
Covalent Bond. Chemically Active. The only elements that are inert are group 18, or 8A.
Active
i am pretty sure that when an atom is chemically active its outer valence shell is not full meaning it is able to form different types of bonds with different elements.
Active. VERY active. Sometimes, EXPLOSIVELY active.
Metals in group one are chemically active as compared to the elements in group three and two. Elements like sodium, potassium, chlorine and fluorine are some of the chemically active elements.
inert
Fluorine
Fluorine is more active.
