The heaviest of these particles is the neutron. Alpha particle has two protons and two neutrons bound together into a particle identical to a helium nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways, that makes its mass to be equal to 2mp + 2mn.

Q. Which subatomic particles have the least mass protons neutrons electrons?
Protons are among the (most, least) massive subatomic particles, and they are found (inside, outside) the nucleus. Electrons are among the (most, least) massive subatomic particles, and they are found (inside, outside) the nucleus.
Q. What particle has no charge?
Neutron
Q. Which particle has the greatest mass?
Within the nucleus of the atom, we find the proton and the neutron. The proton has a positive charge while the neutron has a neutral charge.
Q. Which alpha particle has the greatest mass?
Q. Which emanation has no mass and no charge?
gamma radiation
Q. Which radioisotope has the fastest rate of decay?
37Ca
Q. Which radioisotope has an atom that emits a particle with a mass number of 0 and a charge of 1?
Beta-particle: This particle is emitted when a radioisotope undergoes beta-minus decay process. The charge on the particle is -1 and mass number is 0.
Q. Which type of emission has the highest penetrating power?
gamma particles
Q. What has the lowest penetrating power?
alpha particles
Q. What type of radiation is the most penetrating?
Gamma rays
Q. What are the 3 types of radiation?
The three most common types of radiation are alpha particles, beta particles, and gamma rays.
Q. Is all radiation harmful?
Not all radiation is harmful, and whether or not it is harmful depends on the type of radiation in question and how much (the so-called ‘dose’) you are exposed to. Some types of radiation are known as ‘ionising’.
Q. What is alpha beta gamma decay?
Alpha particles carry a positive charge, beta particles carry a negative charge, and gamma rays are neutral. An alpha particle is made up of two protons and two neutrons bound together. Beta particles are high energy electrons. Gamma rays are waves of electromagnetic energy, or photons.
Q. How do you calculate gamma decay?
Gamma decay equations are also called gamma emission equations. Example #1: Write the equation for the gamma decay of the metastable form of 43-Tc-99. MeV stands for mega electron-volts….Writing Gamma Decay (Emission) Equations.

Q. What is the difference between alpha beta and gamma decay?
Alpha decay forms new element with two fewer protons and two fewer neutrons; Beta decay forms new element with one more proton and one fewer neutron. Gamma decay forms NO new element, but now the element has less energy because energy is released as gamma rays.
Q. What is Gamma charge?
Gamma rays. Gamma rays are waves, not particles. This means that they have no mass and no charge.
Q. What can gamma be stopped by?
Gamma radiation is the most penetrating. It can penetrate air, paper or thin metal. It may only be stopped by many centimetres of lead or many metres of concrete.
Q. How much gamma radiation will kill you?
A dose of 5 Sv (5 Gy) is considered approximately the LD50 (lethal dose for 50% of exposed population) for an acute exposure to radiation even with standard medical treatment. A dose higher than 5 Sv (5 Gy) brings an increasing chance of death above 50%.
Q. Why gamma ray is dangerous?
The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer.
Q. Do gamma rays treat cancer?
You may also hear it called radiotherapy or therapeutic radiology. Radiation therapy kills cancer cells with beams of high-energy X-rays, gamma rays, or charged particles (called electrons or protons). It can be used in many ways.
