Answer:
It's called the shielding effect

It describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell. (I hope this helps)
Answer:
Elements in the same group have the same number of valence electrons.
Explanation: Science.
<span><span>The column of a fractional distillation apparatus should be
aligned vertical to get better separation because
the column is essentially longer. It will prevent channeling in the
column. </span>Therefore column efficiency will be higher if it is as
vertical as possible instead of tilted.<span> Distillation is a process used to separate a mixture of two (or
more) components. In a typical </span>fractional
distillation, a liquid mixture
is heated in the distilling flask and the
process begins.</span>
