CHEMISTRY A LEVEL WITH SATISFIED SOLUTIONS What are the two elements which are exceptions to the electron configuration? - CORRECT-The two exceptions for this is copper and chromium. In both cases, the 4s subshell contains only one electron, even though there are electrons in the 3d subshell. To explain this, its because the 3d subshell is more stable when it is either half full, or completely full. So in the case of chromium, by having only one electron in the 4s subshell, ...

The smallest functional unit in living organisms - Answer- Atoms The three subatomic particles - Answer- protons, neutrons, electrons Where the neutrons and protons are found - Answer- The atomic nucleus What was Rutherford's experiment? - Answer- A fine beam of positively charged alpha particles (helium nuclei) was aimed at an extremely thin sheet of gold. A zinc sulphide screen was used to detect any alpha particles that passed through or bounced off. What shape are "s" orbitals...

Ionization Energy - Answer-energy required to remove an electron from an atom in the gas phase Left Side Electrons - Answer-have weaker attractions to remove electrons *easier to remove electrons from the left side of the table than the right side* Does it take MORE or LESS energy to remove an electron from Li than from Na? - Answer-MORE Why? Because as we move down a group, the orbitals become larger and weaker. While going across the effective nuclear charge increases. (holds onto the ele...
