Question

For the following isotopes that have missing information, fill in the missing information to complete the notation (a) 3414x1434x (b) 36xpx36p (c) 57xmnx57mn (d) 12156x

Answer 1

During the notation of isotopes, Atomic number (Z), and atomic mass (A) are used distinctly.

What do you mean by Isotopes?

Isotopes may be defined as a member of a family of an element that all have the same number of protons but different numbers of neutrons.

• $_14X^3^4$, indicates that atomic number is 14, while atomic mass is 34, where X is Silicon.
• $_XP^3^6$, indicates that the element is Phosphorus, atomic mass is 36, while X is 15 which is atomic number.
• $_XMN^5^7$, indicates that the element is Manganese, atomic mass is 57, while X is the atomic number which is 25.
• $_5_6X^1^2^1$, indicates that the atomic number is 56, while the atomic mass is 121, where X is Barium.

Therefore, it is well described above.

Answer 2

 Isotopes are the species having equal range of electrons and protons however distinct range of neutrons.

What are atomic no.?

Atomic range is the range of electrons gift withinside the atom of the detail.Atomic mass is the range of protons and neutrons gift withinside the atom of the detail.

1. The widespread illustration of an detail is as X A Z.
2. Where A is the atomic range, X is the image of the detail and Zis the atomic mass of the detail.
3. The atomic mass of the detail is written after the hyphen.
4. The atomic mass is 34 and atomic no. is 34 is silicon.
5. Atomic no. is 15 then the values of x is also 15.
6. Atomic mass is 121 and no. is 56 for barium.\
