Write the nuclide notation, including charge if applicable, for atoms with the following characteristics:
(a) 25 protons, 20 neutrons, 24 electrons
(b) 45 protons, 24 neutrons, 43 electrons
(c) 53 protons, 89 neutrons, 54 electrons
(d) 97 protons, 146 neutrons, 97 electrons

A. 25Mn45^+

B. 45Rh69^+2

C. 53I142^-

D. 97Bk^243

Explanation:

Generally Atomic mass (A)= no of protons (p) + no of neutrons (n)

No of Neutrons (n)=A-p

No of protons = Atomic number

Symbol for nulclide: zX^A

Z is Atomic number, A is Atomic mass

And X is symbol of element

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong
