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 charge are neutrons?
neutrons have no charge at all, ther are neutral
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.
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.
Do neutrons have an electric charge?
No Neutrons have no charge at all.-Olivia F.No they are neutral.no they are neutral protons are positive electrons are negative

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).
What is composed mostly of the protons and neutrons in the nucleus?
The nucleus of an atom is composed mostly of protons and neutrons. Protons have a positive charge and neutrons have no charge, together they make up the majority of an atom's mass.
Where does the nucleus get its positive charge from?
The quarks that makeup the protons.
Neutrons and protons are examples of what?
Protons and neutrons are both hadrons, and any hadron is comprised of three of six quarks. A hadron must have an integer charge in terms of a proton's charge (+1), with quarks having a charge of either +2/3 or -1/3.
Which particles in atoms have electrical charges?
The Electrons and the Protons.
Are neutrons positively charged?
Neutrons do not have any electric charge at all but are neutral - hence the name. Even the neutron's antimatter menifestation, the antineutron, is neutral.
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.
