Kr fourth period means the fourth horizontal row on the periodic table....so the element on that row with the highest atomic number is Kr
Selenium, which is in the same group as oxygen.
bromine, i think
Sodium is the fourth most abundant element on earth
plasma is a type of sub atomic particles similar to a gas and sometimes called the fourth state of matter. However all other forms of matter are atomic while plasma is a floating cloud of ionised particles and charged particles like protons and electrons.
It is the fourth least reactive element, followed by Mercury, Gold and Platinum.
Beryllium has atomic no. 4.So it is the fourth element.
Selenium, which is in the same group as oxygen.
one of the chemical element in the fourth row.. i think... pretty sure LOL :)
bromine, i think

The first element in the fourth period of the Periodic Table is potassium (K).
The first element in the actinide series is actinium , a chemical element in the periodic table that has the symbol Ac and atomic number 89.The actinide (or actinoid) series encompasses the 15 chemical elements that lie between actinium and lawrencium on the periodic table , with atomic numbers 89-103.The actinides get their name from the first element in the series , actinium.
the fourth hokage's element specialty is lightning
The first element in the fourth period of the periodic table is potassium (K).
In, Sn, Sb, Te, I or Xe are all representative (main group) elements in the 5th period which is numbered on the left (1-7) and a "period" is the horizontal rows.
the lighest element is berrylium.
ruthenium is the 44th element. It is a transition metal.
