Comments. 1  127.0.0.1 is very reliable, as is ::1 for ipv6. Its a joke..for those who dont know 127.0.0.1 = your own computer. 2  Iâve gotten into the habit of 4.2.2.2/1 over the years, but yeah, I guess I could get used to 8.8.8.8. 3  I still ping 4.2.2.2, Iâm old school.
The electrical charge of the hydrogen atom is thought to be exactly zero. This is a consequence of the apparent equality of the magnitude of the electrical charges of the electron and the proton, and their opposite sign.
These things have the same size charge, but the sign is different. A proton has a charge of +e, while an electron has a charge of -e. Electrons and protons are not the only things that carry charge. Other particles (positrons, for example) also carry charge in multiples of the electronic charge. Those are not going to be discussed, for the most part, in this course, however.
