atom configuration

Cards (11)

  • Protons have a positive charge, while electrons have a negative charge.
  • Neutral atoms contain an equal number of protons and electrons.
  • Ions are charged particles formed when there is an unequal number of protons and electrons.
  • The atomic mass is the sum of the masses of all particles within the nucleus (protons + neutrons) plus the electron cloud's mass.
  • Isotopes are different forms of the same element with varying numbers of neutrons but similar chemical properties.
  • Isotopes are different forms of the same element with varying numbers of neutrons but the same number of protons.
  • Nuclear reactions involve changes in the nuclei of atoms, such as fission or fusion.
  • Atomic radius increases as we move down a group on the periodic table due to increased shielding by inner shells.
  • Orbital diagrams show the arrangement of electrons in orbitals around the nucleus, while box models use boxes to represent energy levels and arrows to indicate filled orbitals.
  • Electron configurations can be represented using orbital diagrams or box models.
  • Incomplete subshells are indicated by unpaired electrons, which may contribute to magnetic properties.
