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.
Neutrons are neutral, but protons and electrons are electrically charged. Protons have a relative charge of +1, while electrons have a relative charge of -1. The number of protons in an atom is called its atomic number. In the periodic table atoms are arranged in atomic number order.
