Give the chemical symbol for the element with the ground‑state electron configuration . symbol: determine the quantum numbers and ℓ and select all possible values for ℓ for each subshell of the element. = ℓ= the possible values of ℓ for the subshell are −3,−2,−1,0,+1,+2,+3 −1,0,+1 −2,−1,0,+1,+2 0 = ℓ= the possible values of ℓ for the subshell are −1,0,+1 −2,−1,0,+1,+2 −3,−2,−1,0,+1,+2,+3 0

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.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
