Since the "ATOM" is the building block of all matter and the only thing we find in an Atom are Negative & Positive Electrical Charges.

The answer just depends on the scale you look at.

At very small scales, the nuclear forces dominate.
At the atomic scales, electromagnetic forces dominate.
EM forces dictate basic physical chemistry, which in turn pretty much describes how everything around us interacts.
At very large scales, gravity dominates, so in a sense you could say we live in a gravitational universe.

Saying that the only things you find in an atom are positive and negative electrostatic charges is an incomplete statement. Keep looking and It's like layers of an onion. There's more and more the deeper you go.

can't have one without the other.

By the way, an atom is made of matter which has mass, not just electrical charges. Protons have mass, but a positive charge does not. The electrical forces as well as the strong and weak forces keep matter together. Gravity also would not work, or exist if the universe were wholly electrical because gravity only works on the mutual attraction of massive particles whereas pure electricity has no mass.

That question IS a conundrum if you limit yourself to earth and earthbound objects, which are made of chemicals which are made of atoms which are made of charges. Then anyone could argue that everything is BOTH chemical AND electrical. BUT, the word UNIVERSE makes this a no brainer! The UNIVERSE is 99% hydrogen. And hydrogen is the simplest element, hardly what anyone would call a "chemical"! And Hydrogen is one positive charge and one negative charge, so the UNIVERSE is ELECTRICAL.

An atom is not just made up of electrical charges. It is made up of particles with mass, some of which carry charge and some of which do not.
