Since, Number of shells in an atom = number of period, therefore, atoms of element in period 4 will have 4 shells.
What are electron shells in periodic table?
Electrons are organized in shells, called energy levels. Each shell has an important quantum number. Shells with a higher head quantum number are further from the core and have a higher energy level.
Electron shells are parted into sublevels called sub-shells. These differ in energy level as well. Sub-shells contain various quantities of orbitals.
Orbitals can hold a limit of two electrons and have various shapes.
Electrons fill shells, sub-shells and orbitals in a specific request, known as a component's electron setup.
The total number of shells occupied in atoms of elements in period 4 will be 4 shells.
