(a)
(b)
(c)
(d)
(a)
Interpretation:
The hyphenated form of isotope
Concept Introduction:
The atomic number is equal to the number of protons of an element whereas sum of number of protons and number of neutrons is equal to mass number.
A form of chemical element having same atomic number but differ by mass number is known as isotopes. In hyphenated form of isotope, the name of chemical element is written before the mass number.
Answer to Problem 1E
sodium-24
Explanation of Solution
Given isotope is
Na is the symbol of sodium.
Mass number of sodium = 24
Atomic number of sodium =11
Therefore, the hyphenated form of
