Explanation / Answer
we know that
number of protons = atomic number (Z)
number of neutrons = mass number (A) - atomic number (Z)
number of electrons = atomic number - charge
so
using this information
1) Na
Z = 12
now
mass number (A) = atomic number (Z) + number of nuetrons
A = 11 + 12
A = 23
so
mass number (A) = 23
number of protons = atomic number = 11
charge = 0
2) S2-
charge = -2
atomic number of sulphur = 16
number of protons = atomic number = 16
number of electrons = atomic number - charge
number of electrons = 16 - (-2) = 18
number of nuetrons = A - Z
number of neutrons 32 - 16 = 16
3) Cr+3
charge = +3
atomic number = 24
number of protons = atomic number = 24
mass number = number of protons + number of neutrons
mass number = 24 + 28
mass number (A) = 52
now
number of elctrons = atomic number - charge
number of electrons = 24 -3 = 21
4)
atomic number = 19
so
it is potassium (K)
charge = atomic number - number of electrons
charge = 19 -19
charge = 0
number of protons = atomic number = 19
mass number= 19 + 19
mass number = 38
so
the table is
Z A p e n charge
Na 11 23 11 11 12 0
S2- 16 32 16 18 16 -2
Cr+3 24 52 24 21 28 3
K 19 38 19 19 19 0
