What is the electron configuration for an electrically neutral atom of neon(Ne)? Use the periodic table.

1s22s22p4

1s22s2

1s22s22p44d2

1s22s22p6

1s22s22p44d2 this may be answer

1s²2s²2p⁶

Explanation:

astronomers such as edwin hubble.

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.
