Atoms combine to form bigger particles called molecules. These molecules are what forms the objects in our surrounding environment. Atoms are comprised of three particles: electrons which have a negative charge, protons which have a positive charge and neutrons which have no charge.
The molecule is symmetric, a tetrahedron. Thus, the 4 polar bonds cancel each other out. (It is easier to see with a one dimensional molecule like CO2, which is linear with the C in the middle. The 2 polar bonds cancel each other.
