What is an ideal gas

A substance whose molecules do not take up space or interact with one another.

PV = nRTThe Ideal Gas Law is the chemistry law that combines the other gas laws (Charles's Law and Boyle's Law).

Symbolically it is: PV = nRT.

Where:

  • P is the pressure of the gas (in atmospheres, ATM)
  • V is the volume of the container (in liters, L)
  • n is the number of moles of gas in the container (in moles)
  • R is universal gas constant (which is 0.0820574587 L · ATM · K-1 · mol-1)
  • T is the temperature of the gas (in Kelvin)

See the Web Links for more information about the Ideal Gas Law, as well as Charles's Law and Boyle's Law.

The principal quantum number for the outermost electrons in a Bromine atom in the ground state is

It is n=4 because Br is in the 4p valence shell.

What is the nuclear decay equation for an example of alpha decay

The equation for the alpha decay of 239Pu is: 94239Pu --> 92235U + 24He

where 24He represents the alpha particle, which is a Helium nucleus.
