Why are the trends and exceptions to the trends in ionization energy observed? check all that apply.
lonization energy tends to increase down a group because the electrons get farther away from the
nucleus.
b lonization energy tends to increase across a period because the nuclear charge increases.
lonization energy tends to increase across a period because electrons are added to the same main
energy level.
the ionization energies of the elements in group 16 tend to be slightly smaller than the elements in
group 15 because the fourth electron is added to an unfilled p orbital.
the ionization energies of elements in group 13 tend to be lower than the elements in group 2
because the full s orbital shields the electron in the p orbital from the nucleus.

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /

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.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
