Structure of MatterWhat is the mass, charge and location of a proton in an atom?

Structure of MatterWhat is the mass, charge and location of a proton in an atom?

Mass = 1 amuCharge = + 1 positive Location = nucleus

Structure of MatterWhat is the mass, charge and location of an electron in an atom?

Mass = Charge = Location =

Structure of MatterWhat is the mass, charge and location of an electron in an atom?

Mass = almost zero (0.0001 amu) too small to count

Charge = -1 negative Location = electron cloud; swarming around, outside the nucleus.

Structure of MatterWhat is the mass, charge and location of an neutron in an atom?

Mass =Charge = Location =

Structure of MatterWhat is the mass, charge and location of an neutron in an atom?

Mass = 1 amuCharge = neutral/zero Location = nucleus

Structure of MatterWhat is the difference between atomic number and atomic mass?

Structure of MatterWhat is the difference between atomic number and atomic mass?

Atomic number is the number of protons and atomic mass is the number of protons + neutrons.
