Assume that oxygen acts like an ideal gas. In other words, assume that the oxygen here satisfies the ideal gas law:
,
where
the pressure on the gas, 
;
the volume of the gas, 
;
the number of moles of the gas, which needs to be found;
the absolute temperature of the gas, 
.
the ideal gas constant, 
if P, V, and T are in their corresponding SI units: Pa, m³, and K.
Apply the ideal gas law to find :
.
In other words, there are 410.3 moles of O₂ molecules in that container.
There are two oxygen atoms in each O₂ molecules. The mass of mole of O₂ molecules will be 
. The mass of 410.3 moles of O₂ will be:
.
What would be the mass of oxygen in the container if the pressure is approximately the same as STP at 
or 
instead?
Ionization energy = the amount of energy it takes for an atom to lose an electron
Remember that the nucleus is positively charged and the electrons are negatively charged. Because those opposite charges attract, the nucleus is pulling the electron towards it and so, the closer an electron is to the nucleus of an atom, the stronger it is being pulled.
Now remember that as more electrons are added to match the number of protons, the shells fill up and each new shell that is made to accommodate for the electrons is further away from the nucleus. That means that the more electrons are in an atom, the more shells there are, and as the shells get further away from the nucleus, the electrons in those shells are pulled with much less force than electrons in the closer shells.
Now all that's left to remember is that as you go down the groups, the elements have bigger numbers of protons and so they have more electrons and so more shells.
Ta da!! Hope that helps!! :D
Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
The best way to prevent the corrosion of iron is to paint the exposed iron with protective paint, because that prevents water from rusting the iron.
