Which is the electron configuration for bromine?
1s²2s22p63s23p4s23d104p5
1s22s²2p3s23p64s23d104p
1s 2s22p63s23p'4s23d104p5
O1s22s22p3s23p64s23dº4p5

12233344 (alternatively 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6)

Explanation:

The correct configuration for bromide () is:

12233344 (it has one more electron in 4p orbital than bromine)

You can also write it as [Ar] , since noble gases are very stable

First can't be correct because there is nothing in 3p orbital and 4p has only 5 electrons here

1s² 2s2 2p6 3s2 3p 4s2 3d10 4p5

Second can't be correct because there is nothing in 2p and 4p orbitales 1s2 2s² 2p 3s2 3p6 4s2 3d10 4p

Third can't be correct because there is nothing in 3p orbital and 4p has only 5 electrons here

1s 2s2 2p6 3s2 3p' 4s2 3d10 4p5

Fourth can't be correct because there is nothing in 2p and 3d orbitales, and 4p has only 5 electrons here

1s2 2s2 2p 3s2 3p6 4s2 3dº 4p5

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
