Answer 1

Respuesta:

$1) \\Li = 1s^{2} -2s^{1} \\B= 1s^{2} - 2s^{2} -2p{1} \\O= 1s^{2}-2s^{2}-2s^{4} \\Ne= 1s^{2}-2s^{2}-2p^{6} \\Cl=1s^{2}-2s^{2}-2p^{6}-3s^{2} -3p^{5} \\\\2)\\Ca= 1s^{2}-2s^{2}-2p^{6}-3s^{2} -3p^{6}-4s^{2} \\- > 8\\Ti=1s^{2}-2s^{2}-2p^{6}-3s^{2} -3p^{6}-4s^{2}-3d^{2} \\ - > 2\\Cr= 1s^{2}-2s^{2}-2p^{6}-3s^{2} -3p^{6}-4s^{1}-3d^{5}\\- > 1\\Mn=1s^{2}-2s^{2}-2p^{6}-3s^{2} -3p^{6}-4s^{2}-3d^{5}\\- > 2\\\\3)\\4d= n= > 4\\n+l= 4+2= 6\\\\6s=n= > 6\\n+l=6+0= 6$
