1.Inaczej absorpcja
6.Twórca modelu atomu wodoru
7.Po niej porusza się elektron w modeu Bohra
8.Jego nazwiskiem nazwano stałą h
9.Następuje, gdy elektron przechodzi na nizszą orbitę

2.Tyle razy promień drugiej orbity jest większy od promienia pierwszej
3.Najmniejsza ilość danego pierwiastka
4.Następuje, gdy elektron przechodzi na wyższą orbitę
5.Krąży wokół jądra


3. Uzupełnij informację dotyczącą atomu wodoru tak, aby była poprawna. Podkreśl słowa, które właściwie uzupełniają poniższy tekst.
-Zgodnie z postulatami Bohra elektron porusza się na danej orbicie po okręgu ze stałą prędkością. Wobec tego musi na niego działać skierowana do środka okręgu siła dośrodkowa/odśrodkowa
-W tym przypadku rolę tej siły odgrywa siła przyciągania grawitacyjnego/elektrostatycznego między protonem/neutronem a elektronem
-Wraz ze zwiększeniem numeru orbity promień orbity zwiększa się/zmniejsza się, a co za tym idzie, wartość siły oddziaływania między protonem, a neutronem/elektronem jest mniejsza/większa
