1. the charge of an atom where the electron is equal to the number of protons. 2. the part of the atom where the mas is concentrated. 3. it is known as the atomic model of joseph thomson. 4. the atomic model of rutherford using gold foil experiment. 5. the negative charge of an atom.

Answer

Brief Explanations:

  1. When the number of electrons equals the number of protons in an atom, the atom is electrically neutral.
  2. The mass of an atom is concentrated in the nucleus which contains protons and neutrons.
  3. Joseph Thomson's atomic model is known as the plum - pudding model.
  4. Rutherford's atomic model from the gold - foil experiment is the nuclear model.
  5. The negative charge in an atom is carried by electrons.

Answer:

  1. Neutral
  2. Nucleus
  3. Plum - pudding model
  4. Nuclear model
  5. Electron
