How many energy shells does arsenic have
WebElectrons are placed into available shells, starting with the lowest energy level. Each shell must be full before the next starts to fill. This model breaks down at the n=3 shell because each shell has subshells. There are 4 … WebA period 4 element is one of the chemical elements in the fourth row (or period) of the periodic table of the chemical elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behaviour of the elements as their atomic number increases: a new row is begun when chemical behaviour begins to repeat, meaning that …
