Suppose you have a sample of potassium Describe several ways you could use periodic trends and a knowledge of valence electrons to predict the element's reactiivity and how the element will behave in a chemical bond.

i don t now

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

i think it is true since you can test the answer and can use observations to complete it.

it would be a gas formation
