Ineed completing this chart. i need to know how to get the charge of an element, the actual number of e- which i believe is beta, and the number of e- in a neutral atom. i also need to know what to do when there is a charge next to the element, are there different steps or the same? i need either steps or answers or both would be even more amazing i’m freaking out it is due soon !

the answer is b & c i believe : )

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.

i think it's letter a.
