Question

scrieti configuratia electronica a elementelor cu z=1 pana la 20 identificand numarul de straturi,substraturi si electroni

Answer 1

configuratia electronica a elementelor  cu:
z=1 este 1s1=> are 1 strat;1 substrat;1 electron
z=2 este: 1s2 => are 1 strat;1 substrat;2 electroni
z=3 este: 1s2 2s1=> are 2 straturi;2 substraturi;3 electroni
z=4 este: 1s2 2s2=> are 2 straturi;2 substraturi;4 electroni
z=5 este: 1s2 2s2 2p1=> are 2 straturi;3 substraturi;5 electroni
z=6 este: 1s2 2s2 2p2=> are 2 straturi;3 substraturi;6 electroni
z=7 este: 1s2 2s2 2p3=> are 2 straturi;3 substraturi;7 electroni
z=8 este: 1s2 2s2 2p4=> are 2 straturi;3 substraturi;8 electroni
z=9 este: 1s2 2s2 2p5=> are 2 straturi;3 substraturi;9 electroni
z=10 este: 1s2 2s2 2p6=> are 2 straturi;3 substraturi;10 electroni
z=11 este: 1s2 2s2 2p6 3s1=> are 3 straturi;4 substraturi ;11 electroni
z=12 este: 1s2 2s2 2p6 3s2=> are 3 straturi;4 substraturi;12 electroni
z=13 este: 1s2 2s2 2p6 3s2 3p1=> are 3 straturi;5 substraturi;13 electroni
z=14 este: 1s2 2s2 2p6 3s2 3p2=> are 3 straturi;5 substraturi;14 electroni
z=15 este: 1s2 2s2 2p6 3s2 3p3=> are 3 straturi;5 substraturi;15 electroni
z=16 este: 1s2 2s2 2p6 3s2 3p4=> are 3 straturi;5 substraturi;16 electroni
z=17 este: 1s2 2s2 2p6 3s2 3p5=> are 3 straturi;5 substraturi;17 electroni
z=18 este: 1s2 2s2 2p6 3s2 3p6=> are 3 straturi;5 substraturi;18 electroni
z=19 este: 1s2 2s2 2p6 3s2 3p6 4s1
=> are 4 straturi;6 substraturi ;19 electroni
z=20 este: 1s2 2s2 2p6 3s2 3p6 4s2
=> are 4 straturi;6 substraturi ;20 electroni
