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 with the atomic number 19.
Sulfur is a fourth period representative element that has similar properties to oxygen. Both elements belong to group 16 of the periodic table, also known as the oxygen group, and have similar chemical reactivity.
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.
The element in the fourth period with atoms that have the same number of electrons in their highest energy level as tin is germanium. Both tin and germanium are in the same group (Group 14) of the periodic table, so they have the same number of valence electrons.
The highest occupied energy level in potassium is the fourth energy level because potassium has 19 electrons, occupying the first three energy levels (with 2, 8, and 8 electrons, respectively) and the remaining electron is in the fourth energy level.
The fourth lightest element on the periodic table is beryllium, with an atomic number of 4.
Beryllium has atomic no. 4.So it is the fourth element.
The first element in the fourth period of the periodic table is potassium with the atomic number 19.
Sulfur is a fourth period representative element that has similar properties to oxygen. Both elements belong to group 16 of the periodic table, also known as the oxygen group, and have similar chemical reactivity.
bromine, i think
The first element in the fourth period of the Periodic Table is potassium (K).
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.
32 electrons on the fourth shell of radon.
the fourth hokage's element specialty is lightning
The element in the fourth period with atoms that have the same number of electrons in their highest energy level as tin is germanium. Both tin and germanium are in the same group (Group 14) of the periodic table, so they have the same number of valence electrons.
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.
