Ka matapakihia e tēnei tuhinga te ariā o te tere o ngā irahiko i roto i te ngota hauwai, te tātai i whakamahia hei tatau, me ōna tono i roto i ngā momo mara.
Ariā Taketake o te Atomi Hauwai
Ko te ngota hauwai, te huānga tuatahi o te ripanga ā-pūmotu, he porotini kotahi i roto i te karihi me te irahiko kotahi e porowhita ana i te karihi. Ko te tauira māmā rawa atu, me te tauira rongonui rawa atu o te ngota hauwai ko te tauira Bohr, i whakaurua mai e Niels Bohr i te tau 1913. E whakaatu ana tēnei tauira i ngā irahiko e porowhita ana i te karihi i roto i ngā porowhita porowhita me ngā taumata pūngao motuhake.
Tauira Bohr o te Atom Hauwai
E ai ki te tauira Bohr, ka taea anake e ngā irahiko i roto i te ngota hauwai te porowhita i ētahi tawhiti mai i te karihi, e mōhiotia ana ko ngā taumata pūngao, ko ngā anga irahiko rānei. Ko ia taumata pūngao he tau matua kua tohua \(n\), ko \(n\) he tauoti pai (1, 2, 3, …). Ko te taumata pūngao iti rawa (n=1) ka kiia ko te āhua whenua, ko ngā taumata pūngao teitei ake ka kiia ko ngā āhua whakaohooho.

Tātai Reiti Irahiko i roto i ngā Ngota Hauwai
Hei tatau i te tere o te irahiko i roto i te ngota hauwai, ka taea e tātou te whakamahi i ngā hua o te tauira Bohr me ngā mātāpono taketake o te miihini irahiko. Ko te tātai mō te tere o te irahiko e homai ana e:
\[ v_n = \frac{e^2}{2 \epsilon_0 h} \cdot \frac{1}{n} \]
Kei hea:
– Ko te tere o te irahiko ko \( v_n \) i te taumata pūngao 9.
– Ko te utu o te irahiko ko \( e \) ( \( 1,602 \times 10^{-19} \) Coulomb).
– Ko te \( \epsilon_0 \) te āheinga korehau ( \( 8,854 \times 10^{-12} \) F/m).
– Ko te pūmau a Planck ko te \( h \) ( \( 6,626 \times 10^{-34} \) Js).
– Ko \( n \) te tau matua o te irahiko.
E whakaatu ana tēnei tātai he rite whakamuri te tere o te irahiko ki te tau matua o te irahiko \(n\). Ko te teitei ake o te taumata pūngao o te irahiko (ko te nui ake \(n\)), ko te puhoi ake o te tere o te irahiko i roto i tōna porowhita.
Tātaitanga Reiti Irahiko
Hei mārama ki te whakamahinga o te tātai i runga ake nei, me mahi tātou i ētahi tātaitanga.
Tauira Tātaitanga: Te Reiti Irahiko i te Taumata Pūngao Tuatahi (n=1)
E mōhiotia ana ko ngā uara o ngā pūmau taketake ko ēnei:
– \( e = 1,602 \times 10^{-19} \) C
– \( \epsilon_0 = 8,854 \times 10^{-12} \) F/m
– \( h = 6,626 \times 10^{-34} \) Js
Mā te whakamahi i te tātai tere irahiko:
\[ v_1 = \frac{e^2}{2 \epsilon_0 h} \cdot \frac{1}{1} \]
\[ v_1 = \frac{(1,602 \times 10^{-19})^2}{2 \cdot 8,854 \times 10^{-12} \cdot 6,626 \times 10^{-34}} \]
\[ v_1 \tata ki te 2,18 \whakareatia ki te 10^6 \, \kuputuhi{m/s} \]
Nō reira, ko te tere o te irahiko i te taumata pūngao tuatahi (n=1) e tata ana ki te \(2,18 \times 10^6\) mita ia hekona.
Tauira Tātaitanga: Te Reiti Irahiko i te Taumata Pūngao Tuarua (n=2)
Mō te taumata pūngao tuarua (n=2):
\[ v_2 = \frac{e^2}{2 \epsilon_0 h} \cdot \frac{1}{2} \]
\[ v_2 = \frac{(1,602 \times 10^{-19})^2}{2 \cdot 8,854 \times 10^{-12} \cdot 6,626 \times 10^{-34}} \cdot \frac{1}{2} \]
\[ v_2 \tata ki te 1,09 \whakareatia ki te 10^6 \, \kuputuhi{m/s} \]
Nō reira, ko te tere o ngā irahiko i te taumata pūngao tuarua (n=2) he tata ki te \(1,09 \times 10^6\) mita ia hekona.
