If you find an element in nature in its pure elemental state, what can you inter about the
element's chemical reactivity? ​

1.)For example water boils at the same temperature no matter how much water you have. You might have 10 grams of water or you might have 20 kilograms of water. The water must reach 100 degrees Celsius in order for the water to start boiling. So the boiling point is an intensive property.

2.)Elements in the each group have the same number of valence electrons. ... If you find an elements in nature in its pure elemental state, what can you infer about the element's chemical reactivity? Low to no reactivity b/c if it did react, it would've bonded with another element

3.) Suppose different parts of a sample material have different compositions. What can you conclude about the material? The material must be a mixture. Suppose different parts of a sample have the same composition.

I an element is found in nature in its pure elemental state then the the element found is not very reactive. There are many elements which are not much reactive. such as in metals- Ag, Au, Hg, Cu etc. and in Non metals- O2, N2, Inert gases etc.

We must learn how to survive with our head but use our hands to help others as well.
