Find the element that makes milk good for your health. is it a metal, nonmetal or metalloid?

Answer is Ca which is a metal.

Explanation: Milk is composed of many elements such as Calcium (Ca), Magnesium(Mg), Phosphorus(P), Potassium (K), Zinc(Zn) ans Selenium(Se). The major component present is Ca.

Calcium present helps in the formation of bones and teeth and maintaining it to keep healthy.

Elements which can loose electrons easily to obtain a stable configuration is called as a metal.

Calcium is a metal as it can easily loose 2 electrons to obtain a stable configuration.

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

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.
