A sample of CO2 occupies a volume of 9.30 liters at 105.5 kPa. What pressure in kPa would the gas exert if the volume was decreased to 2.96 L?

Assuming atoms are shaped like spheres, what subatomic particles would be found in the center? What subatomic particles would be found around the perimeter? Center (nucleus) – protons & neutrons. Perimeter - electrons 3.

The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus. First, let's learn a bit about protons and neutrons, and then we will talk about electrons a little later. Protons and neutrons make up the nucleus of an atom.
