How is it possible that negatively charged beta particles are emitted from a positively charged nucleus during nuclear decay?

An electron (negative particle) and an electron neutrino (neutral particle) are released when a neutron (neutral particle) changes into a proton(positive particle) therefore in order for neutral charge to create a positive particle it also has to create a negative particle to balance it out.
As a significant amount of binding energy is released, the electron is ejected at high velocity as beta radiation while the much more massive nucleus containing the newly created proton recoils with very low velocity. The neutrino having almost no mass is ejected at almost the speed of light, but is nearly impossible to detect except by implication from the "missing momentum".
Basically beta particles are ejected from the nucleus by conservation of momentum before and after the decay event.

This occurs in nuclei with a significant excess of neutrons to protons. To reduce this excess the weak force sometimes changes a neutron to a proton, which ejects an electron (beta particle) and an electron neutrino. This process makes the nucleus even more positively charged (thus conserving charge).

Where does Radio waves travel long distances by bouncing off electrically charged particles?
ionosphere
In which atmosphere layer contains electrically charged particles that reflect radio waves?
The ionosphere - specifically the e-layer
How do you get a magnet red hot?
It is simply done like how your light-bulb works. charged particles(negative) attract positive particles and together they heat up. a good book to get more information on is BC Science probe 6.
Are cathode rays electromagnetic waves?
Cathode rays are not electromagnetic rays because the cathode ray is a beam of electrons that travel from the negatively charged to positively charged end of a vacuum tube, across a voltage difference between the electrodes placed at each end.The electrode at the negative end is called a cathode; the electrode at the positive end is called an anode.Since electrons are repelled by the negative charge, the cathode is seen as the "source" of the cathode ray in the vacuum chamber.
The grid in high-vacuum triode is usally kept negatively charged with respect to the cathode so that the electrons may be?
If this is for your Penn-foster test i can tell you one thing is that the the answer isn't "accelerated toward the anode".
When positively charged particles and negatively charged particles attract each other the substance is?
ionic
What are positively charged particles in an atom called?
Positively charged particles in an atom are called protons.
Are electrons particles that are positively charge?
No, Electrons are negatively charged.
Are atoms normally negatively charged?
No, atoms are not normally negatively charged. They are typically electrically neutral, meaning they have an equal number of protons (positively charged particles) and electrons (negatively charged particles). It is possible for atoms or molecules to gain or lose electrons and become positively or negatively charged, but this is not the usual state.
2 subatomic particles have the same charge?
Protons have positively charged particles, Electrons have negatively charged particles, and Neutrons don't have and charged particles
Which of these subatomic particles is neither positively nor negatively charged?
neutrons
Are electrons the positively charged particles in an atom?
In an atom of antimatter, that would be true, in an atom of matter that would be false.
Is water negatively charged or positively charged?
Water is neutral. This is because it has hydrogen and oxygen particles. One is positively charged, one negatively. This means that they cancel out - water is neutral.
What are the three types of charges that particles can have?
Positive, Neutral, or Negative Positively charged particles are protons Negatively charged particles are electrons Neutrally charged or no charge particles are neutrons
What electrical charge do these parts have?
the protons are positively charged particles neutrons are particles that have no electric charge and electrons are negatively charged particleus.
What are the major types of subatomic particles?
positively charged protons negatively charged electrons neutral neutrons
What is the charge of the 3 subatomic particles are?
Neutron is neutral. Proton is positively charged. Electron is negatively charged.
