The shape is tetrahedral, ideal bond angle(s) is 60 degree, and the direction of any deviation is away from axis from those angles for IF₄⁻.
Bond angles affect how a molecule is structured as well. Bond angles are the angles that connect adjacent lines to form bonds. The bond angle can be used to differentiate between linear, trigonal planar, tetrahedral, trigonal-bipyramidal, and octahedral structures. The VSEPR theory is supported by the ideal bond angles, which demonstrate the maximum angle at which repulsion would be minimized.
In essence, bond angles show that electrons prefer to be far apart. Electrons make up negative ions. The opposites don't attract one another. Now draw a contrast. You don't want to interact with a negative individual because they are often thought of as unpleasant or harsh.
