If protons are positive and are made of two up quarks and one down quark why do neutrons have no charge but are made of two down quarks and one up quark?

The reason that protons are positive and neutrons have no charge is owed to the fact that quarks, which make up these particles, do not have integral charge. The charge of an up quark is +2/3, and the charge of a down quark is -1/3. When the charges of the quarks are added for the particles, we get the following:
Proton = up quark + up quark + down quark = 2/3 + 2/3 - 1/3 = 4/3 - 1/3 = 3/3 = +1
Neutron = up quark + down quark + down quark = 2/3 - 1/3 - 1/3 = 2/3 - 2/3 = 0 (zero)

What is the charge of the center of an atom?
Protons have a positive charge, neutrons are neutral. Gluons are neutral (with respect to electromagnetic charge; they do carry color charge, but that's complicated and comes in 8 different types). Electrons are negative. Quarks have varying charges: up quarks are +2/3, down quarks are -1/3 (quarks also have color charge, but only 3 different kinds).
Which particles in atoms have electrical charges?
The Electrons and the Protons.
What is the name of one types of quarks found in protons and neutrons?
Up quarks and down quarks are in protons and neutrons.
What statement is true about atoms protons neutrons and electrons?
Several come to mind. They are both found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. They are nearly the same size, though neutrons are a bit larger. The sum of the protons and neutrons in an isotope of an element is its mass number.
Atoms are made of what subatomic particles?
All atoms, except Hydrogen-1 which is only one electron and one proton, are made of three fundamental particles: neutrons, protons, and electrons. Neutrons and protons are also made of up and down quarks. Electrons have very little mass and a charge of negative one while protons and neutrons are more massive and of approximately equal mass. Neutrons have no charge (neutral charge) whereas protons have a charge of positive one.
What can a positively charged in an atomic nucleus be?
The atomic nucleus itself has a positive charge. The protons in the nucleus also have a positive charge (the neutrons are neutral). Both protons and neutrons contain "up" quarks, which have a positive charge (the "down" quarks have a negative charge).
What subatomic particle is located inside the nucleus?
The centre of an atom is called the nucleus. The nucleus contains protons, which have a positive charge and neutrons which have no charge. Electrons are also subatomic particles but they go around the nucleus so they are not in the centre.

What particles are found in the nucleus of an atom and what charge do they have?
Without speaking about quarks, leptons and bosons (which are more complicated), the nucleus has neutrons (no charge) and protons (positive charge).
Where does the nucleus get its positive charge from?
The quarks that makeup the protons.
Which particles in atoms have electrical charges?
The Electrons and the Protons.
What is the name of one types of quarks found in protons and neutrons?
Up quarks and down quarks are in protons and neutrons.
what name of one of the types of quarks found in protons and neutrons?
Up quarks and down quarks are in protons and neutrons.
What is is made up of smaller protons and neutrons?
Atoms are made up of Protons and neutrons and electrons. Quarks make up Protons and Neutrons. Protons are made up of 2 up quarks and one down quark. Neutrons are made up of 2 down quarks and 1 up quark. A down quark has a charge of -1/3. An up quark has a charge of +2/3.
What particles contribute to the charge of an atom?
In terms of atomic theory the protons and electroncs contribute the charge to an atom. In terms of quantum theory electrons are a type of lepton and protons are composed of quarks. So quarks and leptons contribute nuclear charge.
What is a comparison with subatomic particles and protons?
Protons are positive, neutrons are neutral, electrons are negative; protons are formed from quarks and gluons.
What statement is true about atoms protons neutrons and electrons?
Several come to mind. They are both found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. They are nearly the same size, though neutrons are a bit larger. The sum of the protons and neutrons in an isotope of an element is its mass number.
