We will get Plagioclase as phenocryst in a porphyritic basalt using Bowmen's reaction series.
Porphyritic basalt is mafic i.e. it has low silica content and have higher melting point than felsic which have higher silica content . Porphyritic basalt's mineral composition is Calcium Plagioclase . Phenocryst is large crystal , early forming igneous rock.
Thus , on cooling plagioclase will be seen as phenocryst which is clear from Bowmen's reaction series because it is present on right side of series at higher temperature range in continuous branch in mafic region.

Answer:
Electronic configuration of Ga³⁺:
Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s⁰ 3d¹⁰ 4p⁰
Explanation:
Gallium is present in group 13.
It has 3 valance electrons.
Electronic configuration:
Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p¹
There are two possibilities of gallium to form cation.
By removing one 4p electron to form Ga +1 cation.
By removing two 4s electrons and one 4p to form Ga +3 cation.
Gallium is preset in group thirteen that's why common oxidation state is +3.
Electronic configuration of Ga⁺:
Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁰
Electronic configuration of Ga³⁺:
Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s⁰ 3d¹⁰ 4p⁰
