How many elements are there in the 4th row of the Periodic Table? Discuss why it is not possible for there to be another element in this row.
There are 18 elements in the 4th row of modern periodic table.
For the 4th row, value of principal quantum number n=4. So, the orbitals present in the outer- most shell will be 4s, 3d, 4p.
So there are total 9 orbitals present in the 4th row, and since 1 orbital can accommodate maximum 2 electrons, so maximum 9×2= 18 elements can be present in the 4th row.

what would be the number of elements in the fourth row of the periodic table? what would be the number pf elements in the third row of the periodic table. i thoight that this would be an easy question, but i have no idea where they got the number “3” for the amount of elements in the first row of the periodic table.

PART A: Based on position in the periodic table and electron configuration, arrange these elements in order of decreasing E11 (ionization energy) . Rank the elements from highest to lowest ionization energy. To rank items as equivalent, overlap them. K, O, Na, P, Al, S PART B: Examine the following set of ionization energy values for a certain element. How many valence electrons does an atom of the neutral element possess? ionization step: ionization energy (kJ/mol): E11 1012 E12 1903...

1 Name a main group element in the fourth period (row) of the periodic table with four valence electrons. Express your answer as a chemical symbol (ex: He).
For each row in the table below, decide whether the pair of elements will form a molecular compound held together by covalent chemical bonds. If the elements will form a molecular compound, check the box and enter the chemical formula and name of the compound. (If the elements will form more than one molecular compound, use the compound with the fewest total number of atoms.) You may assume all chemical bonds are single bonds, not double or triple bonds. molecular...
