What is the name of the element with a valence electron configuration of 2s22p1?

  The  name  of  the  element with  valence   electron    configuration  2s^2 2P^1

  is boron   

Boron  has    electronic  configuration of   1s^2  2S^2  2P1   or   (He)  2s^2 2P^1 . since  Boron is  in  atomic  number  5. boron  has   3  valence   electrons

about what?
have a good day

Hello! data: p (pressure) = 1.25 atmv (volume) = ? (in l)t (temperature) = 298 kn (number of mols) = 0.900 molesr (gas constant) = 0.082 (atm*l/mol*k)apply the data to the clapeyron equation (ideal gas equation), see: i hope this . =)
