Which gas effuses 2.39 times slower than nitrogen gas? Use Graham’s law: VaVb=(mb)1/2(ma)1/2. I2 Br2 O2 Cl2

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above
