The table shows some values of Z, N and A for six different nuclides. Complete the table as follows: Fill in the missing values of Z, N and A in the second, third, and fourth columns. Use the Periodic Table to identify the elements, and write your answer in the fifth column. Finally, in the last column write the symbol for each nuclide in the form ${}_Z{}^{A}X$.

Nuclide	Proton number $Z$	Neutron number $N$	Nucleon number $A$	Name of Element	Nuclide Symbol  ${}_Z{}^{A}X$
Nu-1	$4$	$5$
Nu-2	$5$	$7$
Nu-3		$4$	$8$
Nu-4	$6$		$11$
Nu-5		$6$	$11$
