It is true that when a distance between gas particles increases, the volume of the gas will also increase.
Answer: Option A
<u>Explanation:</u>
The volume of any material can be the space occupied by any material. And the space required by any material to occupy a desired shape or size is determined by its bonding and distance between the particles making that material. If the particles which are soft and small can be compressed easily to occupy very small volume compared to compound made up of hard and large particles.
Along with this, the distance between the neighbouring particles also play a major role, as if we consider a laddo, we can compress it to small size by reducing the distance between neighbouring particles while we will not be able to compress the size or volume occupied by a table as we cannot reduce the distance of particle separation. Thus, it is true that if the distance between gas particles increased then the volume of gas particles will also increase.
Answer:
valence electrons are the ones
<span>The Geiger counter contains a metal tube containing a wire (electrode) and gas. When nuclear radiation (X-ray or Gamma) enters the tube it ionizes the gas (strips electrons from gas atoms) allowing the gas to conduct electricity when the metal tube and electrode are maintained at a voltage differential. A circuit counts the frequency of ionizations. Alpha particles (helium nuclei) can be stopped by a sheet of paper and Beta particles (electrons) are often not energetic enough to penetrate metal.

The Plum Pudding Model is a model of atomic structure proposed by J.J. Thomson in the late 19th century. Thomson had discovered that atoms are composite objects, made of pieces with positive and negative charge, and that the negatively charged electrons within the atom were very small compared to the entire atom.
