scientists knew that oxygen was a element as it had the atoms of only O i,e. oxygen and helped in increase in combustion
Because all of the observations and evidence are used for support.
At what point will scientists gain confidence in a new hypothesisType your answer here...
Scientists learn a few different things. Scientists learn new things very day.
The scientists often revise the hypothesis.
Learning and studying the basics,theories,applications and the latest discovered knowledge of the field. And learning about the new thoughts that scientists exploring now. finally , you should join or work close with some scientists or experts in the field developing your new experiments and theories and checking it.
They can tell whether the nucleus formed is that of a new element or that of an isotope by determining the number of protons inside the nucleus. If the number of protons are different, then it is a different element (not necessarily new). If the number of protons are the same, then it is an isotope.
He is out of his element. The scientists have isolated a new element.
because they are mad
This information is obtained by the study of the decay chain of this product.
essentially that's what a lot of elements are, but what makes an element a new element is if it can be reproduced and be stabilized for an amount of time
An element's ability to react with oxygen is an example of a chemical property. This property describes how elements interact with other substances to form new compounds. In this case, the element's reactivity with oxygen shows its tendency to form oxides.
element
i dont know ;D
Scientists perform artificial transmutation by bombarding the nucleus of an atom with high-energy particles such as protons or neutrons. This can induce a nuclear reaction, causing the atom's nucleus to change, resulting in the creation of a new element or isotope. This process is commonly used in nuclear physics and can be utilized to produce new elements for research or practical applications.
They know by the artifacts they found in the caves.
Because all of the observations and evidence are used for support.
An element has a characteristic number of protons in the nucleus of its atoms. Whenever scientists find an atom with a different number of protons in the nucleus than of any known element, they know that they have discovered a new element.
