CREATE TABLE table_70785 ("Lithium" TEXT, "Sodium" TEXT, "Potassium" TEXT, "Rubidium" TEXT, "Caesium" TEXT)

what is the properties of potassium when lithium is h a l o g e n s and sodium is bromine?
SELECT "Potassium" FROM table_70785 WHERE "Lithium" = 'h a l o g e n s' AND "Sodium" = 'bromine'
SELECT "Potassium" FROM "table_70785" WHERE "Lithium" = 'h a l o g e n s' AND "Sodium" = 'bromine'
