active transport requires the usage of energy in the form of ATP to  move something against is concentration gradient. Facilitated  diffusion is a form of simple diffusion i â¦ n that the substance moves  along with its concentration gradient, but it requires the use of a  transport protein.
Quick Answer. The atomic mass of the element neon is 20.18 amu, or atomic mass units. This number, which appears on the periodic table underneath the chemical symbol for neon, Ne, represents the weighted average of the isotopic masses of neon's isotopes based on their abundance in nature. Continue Reading.
As the atomic masses of the elements in the periodic table increases, the number of atoms in 1 mole of neon, a mole of calcium contains remains the same The atomic number of neon is 10. The atomic number of calcium is 20. compared with a mole of neon a mole of calcium contains an equal number of atoms To determine the molar mass of an element, one must know the elements
