There are at least 50 reasons why you can't.
The only other detail I want to mention just now is that China is NOT directly opposite the US. An area in the Indian Ocean is. So if you were digging to China, you would have to go off at a skew, NOT through the center of the Earth.

No you can't because crossing you will need to obit only by water

It is not possible to dig a hole to China from the U.S. because they are not directly opposite each other, and the Earth’s structure makes digging through its layers extremely challenging. Legal and environmental factors, as well as the practicality of such a project, also make this idea unfeasible.

Nomor atom dan konfigurasi elektron unsur B, Al, Ga, In, dan Tl: B (Boron) = Nomor atom 5, Konfigurasi elektron 2, 3Al (Aluminium) = Nomor atom 13, Konfigurasi elektron 2, 8, 3Ga (Gallium) = Nomor atom 31, Konfigurasi elektron 2, 8, 18, 3In (Indium) = Nomor atom 49, Konfigurasi elektron 2, 8, 18, 18, 3Tl (Thallium) = Nomor atom 81, Konfigurasi elektron 2, 8, 18, 32, 18, 3 2b. Elektron valensi dari atom-atom tersebut:B (Boron) = 3Al (Aluminium) = 3Ga (Gallium) = 3In (Indium) = 3Tl (Thallium) = 3Penjelasan:1a. Konfigurasi elektron unsur bernomor atom 1 sampai 20: Untuk menuliskan konfigurasi elektron, kita perlu mengikuti aturan pengisian elektron dalam kulit atom (K, L, M, N). Setiap kulit memiliki kapasitas maksimum elektron: K = 2, L = 8, M = 18, N = 32. Berikut adalah konfigurasi elektron untuk unsur dengan nomor atom 1 sampai 20: Unsur Nomor Atom Konfigurasi Elektron H 1 1 He 2 2 Li 3 2, 1 Be 4 2, 2 B 5 2, 3 C 6 2, 4 N 7 2, 5 O 8 2, 6 F 9 2, 7 Ne 10 2, 8 Na 11 2, 8, 1 Mg 12 2, 8, 2 Al 13 2, 8, 3 Si 14 2, 8, 4 P 15 2, 8, 5 S 16 2, 8, 6 Cl 17 2, 8, 7 Ar 18 2, 8, 8 K 19 2, 8, 8, 1 Ca 20 2, 8, 8, 2   1b. Elektron valensi dari atom-atom tersebut: Elektron valensi adalah elektron yang berada pada kulit terluar atom. Elektron valensi menentukan sifat kimia suatu unsur.
