Number of valence electrons
Explanation:
The most reactive elements are the most electropositive and electronegative elements.
Francium is the most reactive metal and flourine the most reactive non-metals.
Francium is the most electropositive metal and fluorine is the most electronegative non-metal.
Electropositivity is the ability of an atom to willingly lose its valence electrons. This is typical of metals.
Electronegativity is the ability of atoms to attract the shared electrons to themselves in a bond.
- An element is more reactive than another based on the number of valence electrons it has.
- The valence electrons determines how reactive an atom is or would be.
- Elements that requires just one or two electrons to complete their octet would be highly reactive and dire need to find such electron.
- Also, elements with just an electron above the stable configuration will easily want to lose it.
- Elements with a complete configuration will not be reactive.
The valence electrons are the electrons in the outer most shell of an atom used in chemical bonding.

The answer is 1.6 atm. I just took the quiz.
DNA A and B are probably the most closely related because cells get DNA from the parent cells therefor similar DNA comes from relatives.
Answer : The correct answer is option C.
Explanation:
Astronomers have observed that light from the distant object in the universe is shifted towards the frequency of red color which indicates that those object are receding or moving away from the planet earth.This phenomena was termed as Red shift .Same thing goes for galaxies which are very far away from the planet earth.
Where as if galaxies were moving towards the the planet earth their light would have shifted toward the frequency of blue color termed as blue shift.
Hence, the correct answer is option C.
