WebIn the CH4 molecular structure, 8 electrons are represented as dot structure, whereas four single bonds each contain 2 electrons. As an outcome of the calculation, the outermost valence shell electrons of the CH4 molecule are 4 + 4= 8. So far, we’ve used 8 of the total 8 outermost valence shell electrons available for the CH4 Lewis structure. WebExplanation: In the absence of nucleators water can exist as a supercooled liquid down to −48.3 °C (−54.9 °F; 224.8 K) before freezing. The chemical element with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); this property makes tungsten excellent for use as filaments in light bulbs.
