One isotope of a metallic element has the mass number 67 and 37 neutrons in the nucleus. The cation derived from the isotope has
28 electrons. Write the atomic symbol for this element.
2 answers:
No. Of protons = mass no. - no. Of neutrons
No. Of protons = 67 - 37
= 30
No. Of electrons = 28
Zinc will have 30 protons and 28 electrons. So, it will have +2 charge
Symbol - Zn^+2
Answer:
Zinc: Zn
Explanation:
The mass number of element is 67
mass number = number of protons + number of neutrons
So number of protons = 67-37=30
Thus the atomic number of element is 30
the atom with atomic number 30 is zinc
On losing 2 electrons it will form dipositive ion which will have 28 electrons
The symbol of element is Zn
