What evidence supports the idea that magnesium is needed for healthy bones

Bone health. While most research has focused on the role of calcium in bone health, magnesium is also essential for healthy bone formation. Research from 2013 has linked adequate magnesium intake with higher bone density, improved bone crystal formation, and a lower risk of osteoporosis in females after menopause

Explanation:

what is the question?

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
