What happens to the atomic number when the nucleus releases a beta particle?
When the nucleus releases a beta minus particle the atomic number increase with 1.When the nucleus releases a beta plus particle the atomic number decrease with 1.
What happens to a positively-charged alpha particle that comes near the positively charged nucleus?
This particle is rejected.
What happens to a radioactive nucleus when it emits alpha particle and What happens to a radioactive nucleus when it emits alpha particle?
When a radioactive nucleus emits an alpha particle, it decreases by two protons and two neutrons. This results in a new nucleus with a lower atomic number by 2 and lower mass number by 4. The emitted alpha particle is a helium nucleus (2 protons and 2 neutrons) and carries a positive charge.
What happens to a radioactive nucleus when it emits is gamma particle?
it becomes stable.
What happens to the positively charged alpha particle that comes near the positively charged nucleus?
It will repel
What happens to a positively charged alpha particle that comes near the positively-charged nucleus?

What is the particle that circles the nucleus?
The negative particle that circles the nucleus is the electron.
When an alpha particle is outside the nucleus what happens to it?
It soon captures electrons, becoming an ordinary helium atom.
Describe what happens to the proton number and the mass number when an alpha particle is emitted by a nucleus?
When an alpha particle (helium nucleus) is emitted by a nucleus, the proton number decreases by 2 and the mass number decreases by 4. This is because the alpha particle consists of two protons and two neutrons.
The particle NOT found in the nucleus of the atom is what?
The particle not found in the nucleus is the electron
Is an alpha particle is identical to the nucleus of a?
An alpha particle is identical to the nucleus of Helium atom
