Answer:
molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
B. Representative electrons
Firstly it is best to describe the shape and structure of an atom, an atom's system and structure is like of the solar planet, the heliocentric view where the sun is the neutrons and protons and the planets are the electrons. Moreover, the electrons are outside these neutrons and protons surrounding the entire system of its atomic structure. Its movement is like of a planet.
<span>An energy level also known as electron shell, or just shell is a location around an atom where electrons with a specific energy value, or quantum number may be found.</span>
Explanation:
Divide 67.6% by 201 of mercury
Divide 10.8% by 32 of sulfur
Divide 21.6% by 16 of oxygen
Then divide number by itself .
Example : Divide 2.97 by both sulfer moles and oxygen moles . Multiply by 2 to get whole number
