4 0

Answer:

the number of mol that 60 gram of calcium will have this 1.5 mol.

as number of mole is equal to

n=w/m which is

60/40 which is 1.5 mol

and that of the number of atoms it will have will be 60 over 40 times the algorithm constant 6.223 times 10 to the power 23 which will give 9.0 345 ×10²³

V125BC [204]
Atomic Number of Zinc is 30, means it contains 30 electrons. So, its electronic configuration is as follow,

                                    1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰
As,
          1s², 2s², 2p⁶, 3s², 3p⁶  =  Argon
So,
Electronic configuration of Zinc in shorthand notation is as follow,

malfutka [58]

Answer:

Ne

Explanation:

Atomic number of Ne is 10.

Electronic configuration of Ne:

1s^2 2s^2 2p^6

Octet of Ne is complete . Element having complete octet are stable and behave ideal gas.

N_2 and CH_4 are reactive and hence, does not behave as ideal gas.
