Opposite to covalent bonding, this chemical bond creates two oppositely charged ions. It has lateral branches with alternately arranged leaves and small branchlets with oppositely arranged leaves. Compounds consisting of oppositely charged ions are known as ionic compounds, or salts. This membrane is suspended between two sets of permanent, oppositely aligned, magnets. The gyroid separates space into two oppositely congruent labyrinths of passages. The foliage consists of branchlets with oppositely arranged leaves. Leaves are oblanceolate and are arranged oppositely on the stem. These are perennial herbs with oppositely or almost oppositely arranged leaves.

The oppositely charged regions create an electric field within the air between them. Initial analysis focused on whether antimatter should react the same as matter or react oppositely.
