Asodium atom has an electron configuration of 1s22s22p63s1.if the sodium atom becomes ionized, its new electron configuration will be the same as which element? select one:
a. neon
b. magnesium
c. lithium
d. potassium

there all right good

explanation:

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.
