Q. What is atomic structure of gases?
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. Particles in a: gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.

Q. What are the basic part of atom?
With the exception of hydrogen, all atoms have three main parts. The parts of an atom are protons, electrons, and neutrons. A proton is positively charged and is located in the center or nucleus of the atom.
Q. What subatomic particle has no charge?
The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus. The electrons have a negative electrical charge. An atom usually contains an equal number of positively charged protons and negatively charged electrons.
Q. What particle has the least mass?
electron
Q. Which of the following mass is least?
Mass of 7 g of Ag will be the least as it has least number of moles. Explanation: Smaller is the number of moles present in an atom smaller will be its mass.
Q. Which alpha particle has the least mass?
proton
Q. Which particle has a mass number of 0 and an atomic number of?
Atomic Mass
| Protons, Neutrons, and Electrons | ||
|---|---|---|
| Charge | Mass (amu) | |
| Proton | +1 | 1 |
| Neutron | 0 | 1 |
| Electron | −1 | 0 |
Q. Which emission is the most charged?
Gamma
- These emissions are charged.
- This emission is the most massive (heaviest).
- This emission is the most charged.
- This emission is most dangerous outside of the body.
- This emission is stopped by thin paper or a few centimeters of air.
- This emission can travel through paper, but is stopped by aluminum.
Q. Which type of radioactive emission has a positive charge?
Alpha particles (α) are positively charged and made up of two protons and two neutrons from the atom’s nucleus. Alpha particles come from the decay of the heaviest radioactive elements, such as uranium, radium and polonium.
Q. Which nuclear particle has the greatest positive charge?
Alpha denotes the largest particle, and it penetrates the least. 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.
Q. What are the 3 types of radiation?
There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. The first is an alpha particle.
Q. What is the most damaging nuclear decay to the human body?
Gamma rays are the most harmful external hazard. Beta particles can partially penetrate skin, causing “beta burns”. Alpha particles cannot penetrate intact skin. Gamma and x-rays can pass through a person damaging cells in their path.
