Answer: The correct option is b. Calcium

Explanation: Ocean water consists of a large amount of Chloride (Cl^-), Sulfate (SO_4^{2-}), Magnesium (Mg^{2+}), Sodium (Na^+), Calcium (Ca^{2+}) and Potassium (K^+) ions.

The coral animals absorb calcium element from the ocean to form their skeleton. Then, the calcium ions combine with carbon and oxygen to form calcite.

Hence, the correct option is b.

Which state of matter had the greatest distance the individual particles?
mylen [45]

Particles in gaseous state have the greatest distance between them. This is because the gas particles have a greater kinetic energy because of which they move far apart from each other. If we take water, in steam (water vapor) the particles are far apart from each other when compared to liquid water and solid ice.

Read the following passage.
Archy [21]

Answer is: the discovery of sub atomic particles like electrons.

J. J. Thomson discovered the electron in 1897.  

His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge.  

With this model, he abandoned his earlier hypothesis (the atom was composed of immaterial vortices).  

J.J. Thomson placed two oppositely charged electric plates around the cathode ray. He did experiments using different metals as electrode materials and found that the properties of the cathode ray remained constant no matter what cathode material he used.

Tomson concluded that atoms are divisible and that the corpuscles are their building blocks (atoms are made up of smaller particles).
