Answer:
atoms or molecules
Explanation:
Gas particles are constantly bumping into each other and the borders of their container.
A nanoparticle is larger than an atom. A nanoparticle is usually made from a few hundred atoms. These particles range from 1 nanometers to 100 nanometers. On the other hand an atom ranges from 0.1 nanometers to 105 nanometers. Using the sizes above, one can clearly see and understand that an atom is smaller.
You subtract the atomic number from the atomic mass and you.
should get -125

<h3>Explanation</h3>
Fluorine F is found in the second column from the right end of a modern periodic table. Fluorine is next to and on the left of the noble gas element neon. A neutral fluorine atom is one electron short of neon, which contains 8 electrons in the outermost shell when neutral. As a result, there are 7 electrons in the outermost shell of a fluorine atom.
Fluorine is in period 2. Its electrons occupy two main shells. The second main shell is the outermost shell of F. There are two subshells in the second main shell:
- 2s, which holds up to two electrons, and
- 2p, which holds up to six electrons.
A 2s electron carries less energy than a 2p electron. By Aufbau principle, the seven electrons will fill the two spaces in 2s before moving on the 2p. Among the 7 outermost shell electrons, 
will end up going to 2p.
The only 2s orbital is filled with two electrons. The two 2s electrons will pair up with opposite spins, as seen with the two arrows. Two of the 2p orbitals will contain two electrons. Those electrons will also pair up. The third 2p orbital will contain only one electron. That electron can spin either 
or 
. Here that electron is shown as an upward arrow.
Answer:
Constant pressure of gas must have a constant volume and a constant number of moles of gas. It's equation is the ideal gas law: pV=nRT
Explanation:
The gas state is the most excited state. It doesn't have a definite volume or shape which is why it can be compressed. Gas pressure is basically the result of all the gas particles moving around and colliding against each other and their container. The rate this happens at as well as its force determines the pressure. Since there are many, many of these gas particles in all quantities of gas, the fluctuation of this rate as well as its intesity is nearly constant.
