<u>Answer:</u> The tendency of an element to react is closely related to the number of valence electrons in the element.
<u>Explanation:</u>
Chemical reactivity is defined as the tendency of an element to loose of gain electrons.
Metals tend to loose electrons and so their chemical reactivity is the tendency to loose electrons.
Non-metals tend to gain electrons and so their chemical reactivity is the tendency to gain electrons.
The number of electrons that an element will loose or gain depends on the number of valence electrons present around that element.
<u>For Example:</u> Chlorine has 7 valence electrons and need 1 electron to complete its octet, whereas sulfur has 6 valence electrons and need 2 electrons to complete its octet.
So, chlorine will gain 1 electron easily than sulfur and thus, is more reactive than sulfur.
Hence, the tendency of an element to react is closely related to the number of valence electrons in the element.
Answer:
it looks like deoxyribose...im not sure tho

Because if you change two things then you do not know which one has affected or altered the dependent variable. if you only change one then you know what exactly changed and why
What an electron and a neutron have in common is that <u>each particle exists inside an atom,</u>
Atoms consist of three particles: protons (which are positively charged), electrons (which are negatively charged), and neutrons (which have no charge).
Because the Earth's orbit around the sun is not in the same plane as the Moon's orbit around the Earth.
