How many electrons do h and he have
WebJan 14, 2024 · The helium atom has only one electron on its shell, we have to put only one electron in its orbital and that will go in the 1s orbital as the S orbital can hold a maximum … WebHow many electrons does hydrogen have? Medium. Open in App. Solution. Verified by Toppr. Hydrogen is the first element on the periodic table, with an atomic number of 1. The one means that it has 1 proton, and the number of protons and electrons is the same, so it has 1 electron too.
