On the Periodic Table, a Period is one of the horizontal rows. If an element is last in it's period, then it's on the right hand side of the Periodic Table. There is an inert gas at the end of every Period.
The last element in each period is a noble element. It is non-reactive.
The last element in any period always has its outermost electron in the same type of atomic orbital, either an s or p orbital.
its the 4th period
period 6
The period of an element is determined by electronic configuration.Period is same as the number of energy levels of the element.
The last element in each period is a noble element. It is non-reactive.
Argon is the last element in its period (period 3) because it fills the 3p sublevel, which can hold a maximum of six electrons. After argon, the next element, potassium, begins filling the 4s sublevel in the next period (period 4).
The last element in any period always has its outermost electron in the same type of atomic orbital, either an s or p orbital.
The horizontal rows are called periods. Krypton (atomic number 36) is the last element in the period 4.
Because it has completely filled valence orbitals.
No that does not mean that it means that your period this time was not as long asit normall is
you mean atomic number and it is 28
Then it probably isn't your period. Sounds like spotting
This tells us that argon has a full outer electron shell, making it stable and unreactive. Elements at the end of a period often have filled electron shells, giving them properties different from other elements in the same period.
An element with the electron configuration Ne3s^23p^5 is in period 3 of the periodic table. The electron configuration indicates that the element has 3 energy levels, with the last electron being in the 3p subshell.
