It looks like this
K–Br:
except that there are also two dots both above and below the "Br" in the diagram (there are three lone pairs on Br, and none on K)
See the Related Questions link about Lewis Dot Structures to the left of this answer for more help with electron dot diagrams!
K has no dots with +1 Br has 3 pairs of dots with one dot paired with a K electron with a -1
Ionic bond.
LI " and H "
It depends which diagram, most likely they are electron shells as all elements have
orbital diagram of bromine
Bromine is paramagnetic. This is because the 4p subshell has a value of 4p5. 5 electrons in a p subshell (which has space for 6), means the last electron is unpaired. The unpaired electron gives it the property of paramagnetism. Alternatively, Selenium is diamagnetic, as it has the outer subshell 4p4, meaning no electrons are unpaired.
1s(up,down) 2s(up,down) 2p(up,down)(up,down)(up,down) 3s(up,down) 3p(up,down)(up,down)(up,down) 4s(up,down) 3d(up,down)(up,down)(up,down)(up,down)(up,down) 4p(up,down)(up,down)(up) All the ups+the downs should equal 35, the number of electrons in Bromine.

I had a science question that asked: An electron ______ is the chemical symbol for the element surrounded by as many dots as there are electrons in its outer energy level. That is pretty much the same as yours. I put dot diagram... Meaning electron dot diagram
Electrons shown in an electron dot diagram are the valence electrons. As a "for instance" here, look at hydrogen and lithium. Each one has a single electron in their outer most or valence shell, and so each will be shown by writing the chemical symbol and by adding a single dot. H. Li.
