The option that correctly describes a covalent species that has four electron groups around the central atom are:

  • The ideal bond angle for a four-electron system is 109.5°.
  • If all four electron pairs are bonding pairs, the shape of the system is tetrahedral.
  • A bent shape is observed if there are two bonding pairs and two lone pairs.

What is the  covalent species that has four electron groups around the central atom?

It should be noted that when a molecule have four electron groups and it is been found around the central atom and this will orients the four groups in the direction of a tetrahedron.

However when there are  four atoms attached to these electron groups, in Tetrahedral Geometry, molecular shape  will also be also tetrahedral.

Instance of this is Methane (CH 4), in conclusion, in the case whereby all four electron pairs are bonding pairs, then it can be concluded that the  shape of the system is tetrahedral.

The eletron are not bonding in the system.

A bent shape is observed if there are two bonding pairs and two lone pairs.
