Identify whether the following claim: A chemist in South America claims to have discovered a new element with an atomic mass of 34. is correct or not. Concept introduction: An element is an entity of atoms with the same number of protons in its atomic nuclei. There are 118 elements being identified, out of which, the first 94 elements occur naturally on the Earth with the remaining 24 being the synthetic elements. Chemical elements comprise all the usual matter present in the universe. But the astronomical observations propose that the ordinary visible matter makes up only about 15 % of the matter present in-universe: the remaining is just dark matter, the composition of which is unknown. The history of discovery and the use of elements started with a primitive human civilization that found various native elements like carbon, copper, gold, and sulfur.

I have a question about this problem involving mechanisms and drawing curved arrows for acids and bases. I know we need to identify the nucleophile and electrophile, but are there different types of reactions? For instance, what about Grignard reagents and other types that I might not be familiar with? Can you help me with this? I want to identify the names of the mechanisms for problems 1-14, such as Gilman reagents and others. Are they all the same? Also, could you rewrite it so I can better understand? The handwriting is pretty cluttered. Additionally, I need to label the nucleophile and electrophile, but my main concern is whether those reactions differ, like the "Brønsted-Lowry acid-base mechanism, Lewis acid-base mechanism, acid-catalyzed mechanisms, acid-catalyzed reactions, base-catalyzed reactions, nucleophilic substitution mechanisms (SN1 and SN2), elimination reactions (E1 and E2), organometallic mechanisms, and so forth."
