Answer: An atomic number represent protons in an atom.

Explanation:

An atom consists of electrons, protons, and neutrons. The protons and neutrons are present inside the nucleus of an atom whereas the electrons revolve around the nucleus of an atom.

The number of protons in an atom represents the atomic number of that particular atom. Further, this atomic number determines the place of each atom in the periodic table and its chemical properties.

For example, the mass number of sodium atom is 23 that is number of protons and neutrons. The atomic number of sodium is 11 that means there are 11 protons. The number of neutrons will be 23 - 11 = 12.

A postulate of the kinetic molecular theory is listed.
valina [46]

Answer:

Postulate: Gas particles are extremely small and are far apart.

The activities can be used to demonstrate the postulate is :

<u>Observing colored gas spreading into an inverted jar placed on top of a jar containing the gas</u>

<u />

Explanation:

colored gas spreading into an inverted jar placed on top of a jar containing the gas:

This occur because of two reasons:

1. <em><u>The Gaseous particles are largely spaced . There is large distance between the gases molecule</u></em>

<em><u>2. The gases are in continuous motion . Hence they posses very high kinetic energy . This is the reason they mixes quickly if placed in a jar.</u></em>

<em><u>This occur by the process of diffusion. </u></em>

Diffusion of Gases: The intermixing of particles from the region of high concentration to low concentration.

The coloured gas goes into the space between the gaseous molecule present in the jar.(Gases are far apart)

As soon as the coloured gas is mixed in the jar , It spread quickly by diffusion because , The gaseous particles are extremely small and are far apart.
