Hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium have one valence electron.
A positive ion ( the one that gives the electron) and a negative ion ( the one that accepts).
Lithium
Helium
Hydrogen
The element that has a single electron in the 2p sublevel is boron. The electron configuration of Boron is 1s22s22p1.
The element with one 3d electron is manganese (Mn), which has the electron configuration [Ar] 3d^5 4s^2.
The transition metal element with only one electron in its 5s orbital is copper (Cu).
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
Potassium has one.
By adding one electron to an element with 9 protons and 10 neutrons, you would create a negatively charged ion. The electron would occupy an orbital in the electron cloud, resulting in the element being one electron short of achieving a stable electron configuration. This ion would have a charge of -1 due to the extra electron.
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
The element hydrogen is the simplest atom and the most abundant in the universe. It is composed of one proton and one electron.
