Consider the model of the nitrogen atom. Three concentric circles are shown. Inside the inmost circle are the labels P-7 and N-7. The center circle has red dots at the north and south positions. The outer circle has five red dots evenly spaced around the circle; none of them align with dots in the center ring.

Which electron configuration matches this model?
1s22s22p2
1s22s22p3
1s22s22p4
1s22s22p5

c

Explanation:

because i got it right cuh

c

Explanation:

taking the test rn

it's c. elements are placed in rows based on how may valencies electrons have.

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.
