Area outside the atomic nucleus where the probability of finding electrons is high. the cloud model emphasizes the electron is not in a fixed orbit or distance from the nucleus center.

Orbital

Explanation:

An orbital is the area outside the nucleus where the probability of finding electrons is high.

Quantum mechanics considers the electron as both a particle and a wave. Because of its wave nature, the electron does not move in a fixed orbit. We can only say that we are more likely to find an electron in some areas of space rather than others.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
