Answer:
See explanation
Explanation:
The land around us appears flat because the Earth is just so unimaginably large, and the curvature is extremely small from our point of view. In reality, the land is slightly bendy, which is why certain structures (like very long bridges) need to be constructed with the curvature in mind, with different ends at slightly different elevations. Hope this helps!
Answer:
has 4 electrons in its valence shell.
Explanation:
Silicon has 14 protons, so its neutral atom has also 14 electrons, thus, the electron distribution following the Linus Pauling's diagram is:
1s² 2s²2p⁶ 3s²3p²
Thus, it has 4 electrons in its valence shell (3), likely carbon. So, silicon would have some of the properties of carbon, such as form 4 bonds, and the structure would be similar.
