Hello!
Like many other elements in chemistry, when an atom's valence shell is filled the element becomes stable. Through the octet rule we know that when the very last valence shell becomes filled, the atom is stable and therefore it is highly unlikely for the element to form bonds with that of another.
I hope this helped!
Answer:
1 mole of calcium contains 6.023 
atoms.
Explanation:
1 mole is the amount of a substance that contains exactly 
constituent particles. 1 mole of a substance is always equal to the atomic mass of the element.
Hence, 1 mole of calcium will also have atoms.
Number of atoms in 1 mole calcium = 6.023 atom
Answer: Tyndall effect is the scattering of light due dispersed colloidal particles that does not settle in a solution. Colloidal particles constantly moves because of Brownian motion and blocks or hinders light particles to pass through. Colloidal particles are medium sized particles but smaller enough than suspension.
Explanation:
Explanation:
to remind people that atoms were
