Q. What is the atomic number of aluminum?
13
Q. Which element has more valence electrons neon or oxygen?
Any element in group 18 has eight valence electrons (except for helium, which has a total of just two electrons). Examples include neon (Ne), argon (Ar), and krypton (Kr). Oxygen, like all the other elements in group 16, has six valence electrons.

Q. What is the lightest lepton?
b Neutrinos. The electron neutrino (νe) is the lightest lepton, and in fact the lightest fermion, making it an interesting particle for explaining DM.
Q. Is a pion a lepton?
Hadrons are particles that feel the strong nuclear force, whereas leptons are particles that do not. The proton, neutron, and the pions are examples of hadrons. The electron, positron, muons, and neutrinos are examples of leptons, the name meaning low mass. Leptons feel the weak nuclear force.
Q. Can a muon decay to a pion?
Charged pions most often decay into muons and muon neutrinos, while neutral pions generally decay into gamma rays….Pion.

Q. Is a kaon made of quarks?
What is the quark composition of a hydrogen-3 nucleus, 3H1 ? Any of the baryons or mesons can be made from combinations of up and down quarks. This became known as the neutral kaon. Kaons and pions (and many other particles as well) are composed of quarks.
Q. Do kaons have strangeness?
Kaons are mesons formed by a strange (or anti-strange) quark and an up or down quark. They have strangeness of ± 1.
Q. Are pions gluons?
Pions hold hadrons together to form atomic nuclei. Pions , themselves are bound together by the strong force because they are mesons. Gluons are quanta of the strong-interaction, so they are elementary particles on themselves.
