How may protons does the helium atom have
WebBeryllium is a silvery-white, lustrous, relatively soft metal of group 2 of the periodic table. The metal is unaffected by air or water, even at red heat. When copper and nickel are alloyed with beryllium they not only become much better at conducting electricity and heat, but they display remarkable elasticity. WebThe helium is formed during the natural radioactive decay of elements such as uranium and thorium. These heavy elements were formed before the earth but they are not stable and very slowly, they decay. One mode of decay for uranium is to emit an alpha … Explore this collection of videos on each element in the periodic table.

How may protons does the helium atom have
Did you know?
WebHelium has two electrons, so it can completely fill the 1s 1s orbital with its two electrons. This is written out as 1s^ 2 1s2, referring to the two electrons of helium in the 1s 1s orbital. WebAnswer (1 of 3): Helium has an atomic number of 2. So for an atom to be known as a helium atom, it must have 2 protons. For example, if an atom has 3 protons, it will no longer be oxygen, but will instead be lithium. Any atom that doesn’t have 2 protons is not helium. The amount of electrons mus...
