When an element tends to lose its valence electrons in chemical reactions, it behaves more like a metal.
When an element tends to gain valence electrons in chemical reactions, it behaves more like a nonmetal.
Metalloids have properties intermediate between those of pure metals and pure nonmetals. Usually, metalloids appear in groups where they are sandwiched between nonmetals and metals such as in groups 13, 14 and 15.
The way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.
Given an incomplete sentence related to hypothesis and astronomy.
We are required to complete the sentence.
A hypothesis is basically a testable statement about the relationship between two or more variables or a proposed explanation for some observed phenomenon.
Astronomy is basically the study of everything in the universe beyond Earth's atmosphere.
The statement can be completed by "do experiments and observations about the prediction of the hypothesis".
Hence the way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.
