Krypton is the 36 th element in the periodic table. It is a noble gas belonging to 4th period of the periodic table.
Beryllium has atomic no. 4.So it is the fourth element.
Oh, dude, copper has been chilling on the periodic table since way back in the day. It was discovered way back in ancient times, like before Wi-Fi was even a thing. So yeah, copper has been part of the elemental squad for a looong time.
Elements in the 4th period of the periodic table all have four energy levels or shells in their atomic structure. They belong to the same block (s and p) and exhibit similar chemical properties in terms of reactivity and bonding. Elements in this period include potassium, calcium, scandium, titanium, and iron.
I stands for Iodine, (pronounce: I-o-dine) the 4th element in group 17, atomnumber 53..
Krypton is the 36 th element in the periodic table. It is a noble gas belonging to 4th period of the periodic table.
Be Beryllium, the 4th element on the table and an alkaline earth metal.
Beryllium has atomic no. 4.So it is the fourth element.
Periods are the horizontal rows on the Periodic Table. Cu is in the 4th row. Therefore, copper is in period 4 on the Periodic Table.
Periods are the horizontal rows on the Periodic Table. Cu is in the 4th row. Therefore, copper is in period 4 on the periodic table.
If you think to the atomic radius (empirical) this chemical element is very probable radium.

Chromium is a metal. It is located in the 4th period of the Periodic Table. It is the element with the chemical abbreviation Cr.
The first period in which you'll find 18 elementSis the fourth (4th) period: going from 19-K (potassium) to 36-Kr (Krypton).Maybe this is the answer to the question you didn't ask but probably meant to ask.(It is impossible for one element to contain 18 elements, you see!)The element with 18 electrons in the 3rd period (= row) of the periodic table is ArgonIn the first period of the periodic table there are only two elements: H (1 eln.) and He (2 eln's) and have nothing to do with the number 18.
In the periodic table, the letter "I" typically stands for Iodine. Iodine is a non-metal element with atomic number 53. It is commonly used in the production of disinfectants, as well as in the human body to regulate thyroid function.
Arsenic, which is in the 15th group 4th period of the periodic table of elements and has an atomic number of 33.
Group III-B or 4th, it includes 4 elements of 'd' block and all the 28 elements of 'f' block.
