Explanation:
There are 118 different known <em>elements</em>.
Each element is identified by the number of protons and it is called the atomic number. For instance, the atomic number of hydrogen is 1, every hydrogen atom has one proton; the atomic number of oxygen is 8, every oxygen atom has 8 protons; the atomic number of carbon is 6, every carbon atom has 6 protons.
There are not two different elements with the same atomic number (number of protons).
The 118 known elements are listed in the periodict table in groups (columns) and periods (rows) in increasing order of atomic number (number of protons).
So, by counting the number of protons of an atom, chemists can tell the element to which the atom belong.
The answer would be 69 miles
The number of atoms of fluorine that are present in the molecules of CF4 is calculated as follows
1 x4 = 4 atoms of fluorine
in CF4 they are four atoms of fluorine since the subscribe 4 indicate that they are four atoms of fluorine
