Corn Tortillas (2) 120 cal, no fat, no sodium, 26g carbs, 2g fiber, 4g protein. Getting 2 corn tortillas instead of 4 in the tacos is a great way to cut down on calories without feeling like youâre missing out. The nutrition info says thereâs no sodium in them at all, though I wonder if thatâs a typo.
Helium. Helium. A noble gas with the atomic symbol He, atomic number 2, and atomic weight 4.003. It is a colorless, odorless, tasteless gas that is not combustible and does not support combustion. It was first detected in the sun and is now obtained from natural gas.
Remember that for a neutral atom, the number of electrons must be equal to the atomic number (the number of protons). Electron configurations show the sublevel (1s, 2s, 2p, etc) and the number of electrons in each sublevel as a superscript after the sublevel.Let's try the electron configuration of helium. The atomic number of helium is 2, so a neutral atom of helium must have 2 electrons.The electron configuration would be 1s2.emember that for a neutral atom, the number of electrons must be equal to the atomic number (the number of protons).
