What is the definition of First Ionization Energy? | The energy required to remove one electron from one atom, in one mole of gaseous atoms to form one mole of gaseous 1+ ions. |
What is the first ionization equation of Ne? | Ne(g) -----> Ne+(g) + e- |
What are the three factors effecting ionization energy? | Nuclear Charge Atomic Radius Electron Shielding |
Why are successive ionization energies larger than the one before? | As each electron is removed, there is less repulsion between the electrons and each shell will be drawn in to be slightly closer to the nucleus As the distance of each electron from the nucleus decreases slightly, and nuclear attraction increases. |
How many electrons does an S orbital hold? | 2 |
How many electrons does a P orbital hold? | 6 |
What shape is an S orbital? | Spherical Shape |
What shape is a P orbital? | Dumb-bell Shape |
How many electrons does a D orbital hold? | 10 |
How many electrons does a F orbital hold? | 14 |
What is the definition of a sub-shell? | A group of the same type of atomic orbitals within a shell |
What is the definition of electron configuration? | The arrangement of electrons in an atom |
