Silicon was not widely known until Silicon Valley became prominent because the region became a hub for technological innovation and semiconductor development. Silicon Valley derived its name from the silicon material used in producing semiconductors which are vital components in electronic devices. The success and growth of tech companies in Silicon Valley brought attention to the importance of silicon in the technology industry.

Elements in Group 14 on the Periodic Table have similar properties to carbon. These elements are carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). Each of these elements has two electrons in the outermost p orbital, the electron configuration ns2np2, and they tend to adopt oxidation sates of +4 (+2 for the heavier elements due to the inert pair effect). Silicon is most similar to carbon.
To separate silicon dioxide from the mixture, you can use techniques like filtration or gravity separation since silicon dioxide is insoluble in water and can be easily separated. To separate ammonium chloride and sodium chloride, you can utilize the difference in their solubility. Ammonium chloride is soluble in water, so you can dissolve the mixture in water and then evaporate the water to separate ammonium chloride, leaving behind sodium chloride.
This element is bromine (Br).
chemist used the Periodic Table to make it easier for them to figure out elements.as there are many valuable information(atomic no. 4 example)they can always have the chart with them and see them when they are doing experiments.taching,etc
Homemade silicone rubber is made by melting silicone until it turns into rubber form. Professionally, there are several ways to produce silicone rubber, most are a mixture of silicone, oxygen, carbon and hydrogen.
