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.
Atomic radius. Diagram of a helium atom, showing the electron probability density as shades of gray. The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius.
