Question

A scientist thinks she has discovered a new element. She took some samples to her colleagues and they performed some tests. Here is what they found: the element is a silver, malleable solid at room temperature the element is not very reactive with metals the element has 4 valence electrons the element has 32 protons in its nucleus Which of the discoveries listed above is the most influential in proving her theory incorrect?

Answer 1

Answer:

Proton number of the supposed discovery debunked the theory.

Explanation:

Proton number of an element is also its atomic number.

For the element in question to have had a proton number that wasn't 119, it could not have been a new element.

Furthermore, the characteristics described (proton number especially) describe exactly the Germanium element.

I believe this was helpful.
