Question

why the atomic number of the daughter element is increased by one unit formed by emissions of a β particle​

Answer 1

Answer:

ẞ DECAY

Explanation:

★ RADIOACTIVITY ★

» (ẞ- )DECAY is considered in most of cases and it involves Electron.

» INSIDE THE ATOM ;

1 ] [ Reactant side ]

a . Parent Nucleus

ATOMIC NO. = Z

Mass No. = M

_______________________________________

2 ] PRODUCT SIDE

A) ★Daughter NUCLEUS

Atomic No. = Z + 1

Mass No. = A

B ) ★ ẞ Particle

Atomic No. = - 1

Mass No. = 0

C ) Anti - Nuetrino

★ Charge and Mass less

D ) Q ( Total Energy )

________________________________________

★ TO BALANCE MASS AND CHARGE ON BOTH .. REACTANTS AND PRODUCT SIDE .. IS THE AIM OF " NUCLEAR REACTION " .

» So to Counter ; ( - 1 ) charge of ẞ Particle ;

» Daughter NUCLEUS takes becomes

NUCLEUS takes becomes ( Z + 1 ) .

[ Increases it's Atomic number unit by 1 ]

________________________________________

[ ★ PARENT NUCLEUS AND DAUGHTER NUCLEUS ARE ISOBARS ( SAME MASS ) ★ ]

Answer 2

Answer:

when a beta particle is formed it is actually form due to conversion of of neutron into proton and electron and since electron cannot reside inside nucleus therefore it emits out as beta particle but as you can see atomic number is equal to the number of protons inside nucleus and when a neutron emits a proton this causes increase in atomic number by 1
