What information about elements can be collected from the periodic table?

A lot

Explanation:

- As you go down a group, the elements get larger in size

- All of the elements of the same group have the same # of valence electrons

- As you go to the right of a period, the # of electrons in the outermost shell increases

- The elements at the top right of the table have the highest electronegativity

- Groups 13 through 17 are nonmetals

- The last group contains noble gases

etc.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
