WebHelium is an electron-filled element. The last orbit of helium is full of electrons. Therefore, helium is an inert element and helium atoms are more stable. Therefore, helium atoms do not want to become ions very easily. It takes a lot of energy to turn a helium atom into … Web1 dag geleden · Download PDF Abstract: We study the dynamics of avalanche ionization of pure helium nanodroplets activated by a weak extreme-ultraviolet (XUV) pulse and driven by an intense near-infrared (NIR) pulse. In addition to a transient enhancement of ignition of a nanoplasma at short delay times $\sim200$~fs, long-term activation of the …

WebAccordingly, the group of helium is two but helium is an inert element. All inert elements are placed in group number 18 in the periodic table. Therefore, helium is placed in group-18 instead of group-2. Why is helium an inert gas? The elements in group-18 of the periodic table are inert gases.
