WebSilicon (Si) Question 8 300 seconds Q. A scientist spilled a few drops of dilute hydrochloric acid (HCl) on a lab table.For safety purposes, the scientist sprinkled some baking soda (NaHCO3) onto the spill. Which observation would provide the best evidence that a chemical reaction occurred? answer choices WebSolution. Down the group, the size increases, tendency to show catenation decreases. The more the bond energy, the more is the catenation. The catenation tendency of C,Si and …

WebC and Si are non-metals, Ge a metalloid, and Sn and Pb are soft metals with low melting points. Melting and Boiling Points The melting and boiling point of carbon, silicon, and germanium is significantly high because they have a very stable solid structure. WebGroup IVA elements: C, Si, Ge, having 4 electrons in the valence shell as shown in Figure below form compounds by sharing electrons with other elements without forming ions. This shared electron bonding is known as covalent bonding. Note that the center atom (and the others by extension) has completed its valence shell by sharing electrons. how to start spectrum service

WebApr 4, 2024 · C > Si > Ge > Pb > Sn The lead (Pb) has a high melting point in comparison with tin (Sn) because tin (Sn) forms a distorted 12 coordinated structure and not a pure one. Further, lead atoms are bonded by metallic bonds while the tin atoms are bonded covalently. And we know that covalent bonds are weaker in nature and as a result, these will be ...
