Question

charge number increase by one during ​

Answer 1

Answer:

when moving down to up from a period

Answer 2

Charge number increases by one during beta decay( a type of radioactive decay).

• During beta decay, the proton stays intact. The neutron transforms to form a proton and also a high energy electron.

• The electron exits in the form of a beta particle.

• The changes that take place during a beta decay are:

1. Mass number-  unchanged

2. Atomic number- increased by 1

3. Nuclear charge- increased by 1.

Example: The beta decay of carbon-14

A neutron transforms to form a proton and a beta particle( electron) is emitted, as a result of which nitrogen atom is obtained.
