An element E loses one `alpha` and `beta`-particles in three successive stages. The resulting element will be

A

an isobar of E

B

an isotone of E

C

an isotope of E

D

E itself

Text Solution

Verified by Experts

The correct Answer is:
C
`._(Z)^(A)Eoverset(-alpha)rarr _(Z-2)^(A-4)X overset(-beta)rarr _(Z-1)^(A-4)Y overset(-beta)rarr_(" "Z)^(A-4)W`
Both elements E and W have same atomic number but different mass numbers. Hence, both are isotopes. So, the resulting element will be an isotope of E.

An element X loses one alpha- and two beta- particles in three successive stages. The resulting element will be

alpha -particles and beta -particles

An alkaline earth metal is radioactive. It and its daughter element decay by emitting 3 alpha - particles in succession. In what group should the resulting element be formed?

A radio-active elements emits one alpha and beta particles then mass no. of daughter element is :

A nucleus ._n X^m emits one alpha and one beta particles. The resulting nucleus is.

In the disintegration of a radioactive element, alpha - and beta -particles are evolved from the nucleus. ._(0)n^(1) rarr ._(1)H^(1) + ._(-1)e^(0) + Antineutrino + Energy 4 ._(1)H^(1) rarr ._(2)He^(4) + 2 ._(+1)e^(0) + Energy Then, emission of these particles changes the nuclear configuration and results into a daughter nuclide. Emission of an alpha -particles results into a daughter element having atomic number lowered by 2 and mass number by 4, on the other hand, emission of a beta -particle yields an element having atomic number raised by 1. A radioactive element belongs to III B group, it emits ona alpha - and beta -particle to form a daughter nuclide. The position of daughter nuclide will be in

An element _(z)M^(A) undergoes an alpha - emission followed by two successive beta- emission. The element formed is ……
