Selenium, which is in the same group as oxygen.
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
The symbol for the fourth period alkaline element is K, which stands for potassium.
The first element in the fourth period of the periodic table is potassium with the atomic number 19.
The element with atomic number 4 is Beryllium (Be). Beryllium is the first element in the Group 2 - Alkaline Earth Metals family. It has 4 electron sin two shells, with two electrons in each shell.
Cobalt and nickel. They were placed before expected elements based on increasing atomic mass due to their similar chemical properties, violating Mendeleev's original periodic law.
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
The first element in the fourth period of the Periodic Table is potassium (K).
the fourth hokage's element specialty is lightning
The first element in the fourth period of the periodic table is potassium (K).
The fourth lightest element on the periodic table is beryllium, with an atomic number of 4.
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.
Lithium has a letter 'H' as the fourth letter.
The element in the fourth period with 3 3d electrons is titanium (element #22).
Carbon (after hydrogen, helium and oxygen).
The symbol for the fourth period alkaline element is K, which stands for potassium.
the fourth elements or the fourth dimension in the relativity is time. The space are the first three dimensions.
Two elements, anything in the same column as it, so how about, lithium, and sodium? I'm pretty sure. Lithium and sodium have similar chemical properties to potassium as they are in the same group of the periodic table. They are in group one of the periodic table and are known as the 'alkali metals'. Nearly all elements that are in the same group have similar chemical properties. Common characteristics of alkali metals include: Soft/low density metals React readily with oxygen and water They will react with water to form an alkaline solution and give off hydrogen gas
